Spark NLP for Healthcare Installation

 

Install NLP libraries on Ubuntu

For installing John Snow Labs NLP libraries on an Ubuntu machine/VM please run the following command:

wget https://setup.johnsnowlabs.com/nlp/install.sh -O - | sudo bash -s -- -a PATH_TO_LICENSE_JSON_FILE -i -r

This script will install Spark NLP, Spark NLP for Healthcare, Spark OCR, NLU and Spark NLP Display on the specified virtual environment. It will also create a special folder, ./JohnSnowLabs, dedicated to all resources necessary for using the libraries. Under ./JohnSnowLabs/example_notebooks you will find some ready to use example notebooks that you can use to test the libraries on your data.

For a complete step by step guide on how to install NLP Libraries check the video below:

Install John Snow Labs NLP Libraries on Ubuntu

The install script offers several options:

  • -h show brief help
  • -i install mode: create a virtual environment and install the library
  • -r run mode: start jupyter after installation of the library
  • -v path to virtual environment (default: ./sparknlp_env)
  • -j path to license json file for Spark NLP for Healthcare
  • -o path to license json file for Spark OCR
  • -a path to a single license json file for both Spark OCR and Spark NLP
  • -s specify pyspark version
  • -p specify port of jupyter notebook

Use the -i flag for installing the libraries in a new virtual environment.

You can provide the desired path for virtual env using -v flag, otherwise a default location of ./sparknlp_env will be selected.

The PATH_TO_LICENSE_JSON_FILE parameter must be replaced with the path where the license file is available on the local machine. According to the libraries you want to use different flags are available: -j, -o or -a. The license files can be easily downloaded from My Subscription section in your my.JohnSnowLabs.com account.

To start using Jupyter Notebook after the installation of the libraries use the -r flag.

The install script downloads a couple of example notebooks that you can use to start experimenting with the libraries. Those will be availabe under ./JohnSnowLabs/example_notebooks folder.

Install via Docker

A docker image that contains all the required libraries for installing and running Spark NLP for Healthcare is also available. However, it does not contain the library itself, as it is licensed, and requires installation credentials.

Make sure you have a valid license for Spark NLP for Healthcare (in case you do not have one, you can ask for a trial here ), and follow the instructions below:

Instructions

  • Run the following commands to download the docker-compose.yml and the sparknlp_keys.txt files on your local machine: 
    curl -o docker-compose.yaml https://github.com/JohnSnowLabs/spark-nlp-workshop/blob/513a4d682f11abc33b2e26ef8a9d72ad52a7b4f0/jupyter/docker_image_nlp_hc/docker-compose.yaml
curl -o sparknlp_keys.txt https://raw.githubusercontent.com/JohnSnowLabs/spark-nlp-workshop/master/jupyter/docker_image_nlp_hc/sparknlp_keys.txt
  • Download your license key in json format from my.JohnSnowLabs.com
  • Populate License keys in sparknlp_keys.txt file.
  • Run the following command to run the container in detached mode:
 docker-compose up -d
  • By default, the jupyter notebook runs on port 8888 - you can access it by typing localhost:8888 in your browser.

Troubleshooting

  • Make sure docker is installed on your system.
  • If you face any error while importing the lib inside jupyter, make sure all the credentials are correct in the key files and restart the service again.
  • If the default port 8888 is already occupied by another process, please change the mapping.
  • You can change/adjust volume and port mapping in the docker-compose.yml file.
  • You don’t have a license key? Ask for a trial license here.

Install locally on python

You can install the Spark NLP for Healthcare package by using:

pip install -q spark-nlp-jsl==${version} --extra-index-url https://pypi.johnsnowlabs.com/${secret.code} --upgrade

{version} is the version part of the {secret.code} ({secret.code}.split('-')[0]) (i.e. 2.6.0)

The {secret.code} is a secret code that is only available to users with valid/trial license.

You can ask for a free trial for Spark NLP for Healthcare here. Then, you can obtain the secret code by visiting your account on my.JohnSnowLabs.com. Read more on how to get a license here.

Setup AWS-CLI Credentials for licensed pretrained models

Starting from Spark NLP for Healthcare version 2.4.2, you need to first setup your AWS credentials to be able to access the private repository for John Snow Labs Pretrained Models. You can do this setup via Amazon AWS Command Line Interface (AWSCLI).

Instructions about how to install AWSCLI are available at:

Installing the AWS CLI

Make sure you configure your credentials with AWS configure following the instructions at:

Configuring the AWS CLI

Please substitute the ACCESS_KEY and SECRET_KEY with the credentials available on your license json file. This is available on your account from my.JohnSnowLabs.com. Read this for more information.

Start Spark NLP for Healthcare Session from python

The following will initialize the spark session in case you have run the Jupyter Notebook directly. If you have started the notebook using pyspark this cell is just ignored.

Initializing the spark session takes some seconds (usually less than 1 minute) as the jar from the server needs to be loaded.

The {secret.code} is a secret code that is only available to users with valid/trial license.

You can ask for a free trial for Spark NLP for Healthcare here. Then, you can obtain the secret code by visiting your account on my.JohnSnowLabs.com. Read more on how to get a license here.

You can either use our convenience function to start your Spark Session that will use standard configuration arguments:

import sparknlp_jsl
spark = sparknlp_jsl.start(SECRET)

Or use the SparkSession module for more flexibility:

from pyspark.sql import SparkSession

def start(SECRET):
    builder = SparkSession.builder \
        .appName("Spark NLP Licensed") \
        .master("local[*]") \
        .config("spark.driver.memory", "16G") \
        .config("spark.serializer", "org.apache.spark.serializer.KryoSerializer") \
        .config("spark.kryoserializer.buffer.max", "2000M") \
        .config("spark.jars.packages", "com.johnsnowlabs.nlp:spark-nlp_2.12:"+PUBLIC_VERSION) \
        .config("spark.jars", "https://pypi.johnsnowlabs.com/"+SECRET+"/spark-nlp-jsl-"+JSL_VERSION+".jar")
      
    return builder.getOrCreate()

spark = start(SECRET)

If you want to download the source files (jar and whl files) locally, you can follow the instructions here.

Install on Databricks

Automatic deployment of John Snow Labs NLP libraries

You can automatically deploy John Snow Labs libraries on Databricks by filling in the form available here. This will allow you to start a 30-day free trial with no limit on the amount of processed data. You just need to provide a Databricks Access Token that is used by our deployment script to connect to your Databricks instance and install John Snow Labs NLP libraries on a cluster of your choice.

Manual deployment of Spark NLP for Healthcare

  1. Create a cluster if you don’t have one already

  2. On a new cluster or existing one you need to add the following to the Advanced Options -> Spark tab, in Spark.Config box:

     spark.kryoserializer.buffer.max 1000M
 spark.serializer org.apache.spark.serializer.KryoSerializer
 spark.driver.extraJavaOptions -Dspark.jsl.settings.pretrained.credentials.secret_access_key=xxx -Dspark.jsl.settings.pretrained.credentials.access_key_id=yyy
    • Please add the following to the Advanced Options -> Spark tab, in Environment Variables box:
     SPARK_NLP_LICENSE=zzz

    Note: Spark-NLP for Healthcare also support reading the license from the Databricks DFS, on the fixed location, dbfs:/FileStore/johnsnowlabs/license.key. The precedence for that location is the highest, so make sure that file is not containing any outdated license key.

    • (OPTIONAL) If the environment variables used to setup the AWS Access/Secret keys are conflicting with the credential provider chain in Databricks, you may not be able to access to other s3 buckets. To access both JSL repos with JSL AWS keys as well as your own s3 bucket with your own AWS keys), you need to use the following script, copy that to dbfs folder, then go to the Databricks console (init scripts menu) to add the init script for your cluster as follows:
     %scala
 val script = """
 #!/bin/bash

 echo "******** Inject Spark NLP AWS Profile Credentials ******** "

 mkdir ~/.aws/

 cat << EOF > ~/.aws/credentials
 [spark_nlp]
 aws_access_key_id=<YOUR_AWS_ACCESS_KEY>
 aws_secret_access_key=<YOUR_AWS_SECRET_KEY>
 EOF

 echo "******** End Inject Spark NLP AWS Profile Credentials  ******** "

 """
  3. In Libraries tab inside your cluster you need to follow these steps:
    • Install New -> PyPI -> spark-nlp -> Install
    • Install New -> Maven -> Coordinates -> com.johnsnowlabs.nlp:spark-nlp_2.12:${version} -> Install
    • Please add following jars:
      • Install New -> python Whl -> upload https://pypi.johnsnowlabs.com/${secret.code}/spark-nlp-jsl/spark_nlp_jsl-${version}-py3-none-any.whl
      • Install New -> Jar -> upload https://pypi.johnsnowlabs.com/${secret.code}/spark-nlp-jsl-${version}.jar
  4. Now you can attach your notebook to the cluster and use Spark NLP!

Windows Support

In order to fully take advantage of Spark NLP on Windows (8 or 10), you need to setup/install Apache Spark, Apache Hadoop, Java and a Pyton environment correctly by following the following instructions: https://github.com/JohnSnowLabs/spark-nlp/discussions/1022

How to correctly install Spark NLP on Windows

Follow the below steps to set up Spark NLP with Spark 3.1.2:

  1. Download Adopt OpenJDK 1.8
    • Make sure it is 64-bit
    • Make sure you install it in the root of your main drive C:\java.
    • During installation after changing the path, select setting Path
  2. Download the pre-compiled Hadoop binaries winutils.exe, hadoop.dll and put it in a folder called C:\hadoop\bin from https://github.com/cdarlint/winutils/tree/master/hadoop-3.2.0/bin
    • Note: The version above is for Spark 3.1.2, which was built for Hadoop 3.2.0. You might have to change the hadoop version in the link, depending on which Spark version you are using.

  3. Download Apache Spark 3.1.2 and extract it to C:\spark.

  4. Set/add environment variables for HADOOP_HOME to C:\hadoop and SPARK_HOME to C:\spark.

  5. Add %HADOOP_HOME%\bin and %SPARK_HOME%\bin to the PATH environment variable.

  6. Install Microsoft Visual C++ 2010 Redistributed Package (x64).

  7. Create folders C:\tmp and C:\tmp\hive
    • If you encounter issues with permissions to these folders, you might need to change the permissions by running the following commands: 
      %HADOOP_HOME%\bin\winutils.exe chmod 777 /tmp/hive
%HADOOP_HOME%\bin\winutils.exe chmod 777 /tmp/

Requisites for PySpark

We recommend using conda to manage your python environment on Windows.

  • Download Miniconda for python 3.8
  • See Quick Install on how to set up a conda environment with Spark NLP.
  • The following environment variables need to be set:
    • PYSPARK_python=python
    • Optionally, if you want to use the Jupyter Notebook runtime of Spark:
      • first install it in the environment with conda install notebook
      • then set PYSPARK_DRIVER_python=jupyter, PYSPARK_DRIVER_python_OPTS=notebook
    • The environment variables can either be directly set in windows, or if only the conda env will be used, with conda env config vars set PYSPARK_python=python. After setting the variable with conda, you need to deactivate and re-activate the environment.

Now you can use the downloaded binary by navigating to %SPARK_HOME%\bin and running

Either create a conda env for python 3.6, install pyspark==3.1.2 spark-nlp numpy and use Jupyter/python console, or in the same conda env you can go to spark bin for pyspark –packages com.johnsnowlabs.nlp:spark-nlp_2.12:3.4.4.

Use on Google Colab

Run the following code in Google Colab notebook and start using Spark NLP right away.

The first thing that you need is to create the json file with the credentials and the configuration in your local system.

{
  "PUBLIC_VERSION": "3.2.3",
  "JSL_VERSION": "{version}",
  "SECRET": "{version}-{secret.code}",
  "SPARK_NLP_LICENSE": "xxxxx",
  "AWS_ACCESS_KEY_ID": "yyyy",
  "AWS_SECRET_ACCESS_KEY": "zzzz"
}

If you have a valid floating license, the license json file can be downloaded from your account on my.JohnSnowLabs.com on My Subscriptions section. To get a trial license please visit

Then you need to write that piece of code to load the credentials that you created before.


import json
import os

from google.colab import files

license_keys = files.upload()

with open(list(license_keys.keys())[0]) as f:
  license_keys = json.load(f)

# Defining license key-value pairs as local variables
locals().update(license_keys)

# Adding license key-value pairs to environment variables
os.environ.update(license_keys)

# This is only to setup PySpark and Spark NLP on Colab
!wget https://raw.githubusercontent.com/JohnSnowLabs/spark-nlp-workshop/master/jsl_colab_setup.sh

# -p is for pyspark (by default 3.1.1)
!bash jsl_colab_setup.sh

Spark NLP quick start on Google Colab is a live demo on Google Colab that performs named entity recognitions for HealthCare.

Install on GCP Dataproc

  1. Create a cluster if you don’t have one already as follows.

At gcloud shell:

gcloud services enable dataproc.googleapis.com \
  compute.googleapis.com \
  storage-component.googleapis.com \
  bigquery.googleapis.com \
  bigquerystorage.googleapis.com

REGION=<region>

BUCKET_NAME=<bucket_name>
gsutil mb -c standard -l ${REGION} gs://${BUCKET_NAME}

REGION=<region>
ZONE=<zone>
CLUSTER_NAME=<cluster_name>
BUCKET_NAME=<bucket_name>

You can set image-version, master-machine-type, worker-machine-type, master-boot-disk-size, worker-boot-disk-size, num-workers as your needs. If you use the previous image-version from 2.0, you should also add ANACONDA to optional-components. And, you should enable gateway. As noticed below, you should explicitly write JSL_SECRET and JSL_VERSION at metadata param inside the quotes. This will start the pip installation using the wheel file of Licensed SparkNLP!

gcloud dataproc clusters create ${CLUSTER_NAME} \
  --region=${REGION} \
  --network=${NETWORK} \
  --zone=${ZONE} \
  --image-version=2.0 \
  --master-machine-type=n1-standard-4 \
  --worker-machine-type=n1-standard-2 \
  --master-boot-disk-size=128GB \
  --worker-boot-disk-size=128GB \
  --num-workers=2 \
  --bucket=${BUCKET_NAME} \
  --optional-components=JUPYTER \
  --enable-component-gateway \
  --metadata 'PIP_PACKAGES=google-cloud-bigquery google-cloud-storage spark-nlp-display
  https://s3.eu-west-1.amazonaws.com/pypi.johnsnowlabs.com/JSL_SECRET/spark-nlp-jsl/spark_nlp_jsl-JSL_VERSION-py3-none-any.whl' \
  --initialization-actions gs://goog-dataproc-initialization-actions-${REGION}/python/pip-install.sh

  1. On an existing one, you need to install spark-nlp and spark-nlp-display packages from PyPI.

  2. Now, you can attach your notebook to the cluster and use Spark NLP via following the instructions. The key part of this usage is how to start SparkNLP sessions using Apache Hadoop YARN cluster manager.

3.1. Read license file from the notebook using GCS.

3.2. Set the right path of the Java Home Path.

3.3. Use the start function to start the SparkNLP JSL version such as follows:

def start(secret):
    builder = SparkSession.builder \
        .appName("Spark NLP Licensed") \
        .config("spark.serializer", "org.apache.spark.serializer.KryoSerializer") \
        .config("spark.kryoserializer.buffer.max", "2000M") \
        .config("spark.jars.packages", "com.johnsnowlabs.nlp:spark-nlp_2.12:"+PUBLIC_VERSION) \
        .config("spark.jars", "https://pypi.johnsnowlabs.com/"+SECRET+"/spark-nlp-jsl-"+JSL_VERSION+".jar")

    return builder.getOrCreate()

spark = start(SECRET)

As you see, we did not set .master('local[*]') explicitly to let YARN manage the cluster. Or you can set .master('yarn').

Install on AWS SageMaker

  1. Access AWS Sagemaker in AWS.
  2. Go to Notebook -> Notebook Instances.
  3. Create a new Notebook Instance, follow this Instructions Steps
  4. Minimum requirement 16G RAM and 50G Volume. This is the configuration we have used, although most of the interesting models will require a ml.t3.xlarge instance or more. Reserve at least 50GB of memory
  5. Once created, open JupyterLab and use Conda python 3 kernel.
  6. Upload license key and set Environment Variables.
import json
import os

with open('spark_nlp_for_healthcare.json', 'r') as f:
    for k, v in json.load(f).items():
        %set_env $k=$v

%set_env PYSPARK=3.2.2
%set_env SPARK_HOME=/home/ec2-user/SageMaker/spark-3.2.2-bin-hadoop2.7
  1. Download and install libraries
!wget https://raw.githubusercontent.com/JohnSnowLabs/spark-nlp-workshop/master/jsl_sagemaker_setup.sh
!bash jsl_sagemaker_setup.sh
  1. Import libraries and start session
import sparknlp
import sparknlp_jsl
from pyspark.sql import SparkSession

spark = sparknlp_jsl.start(license_keys['SECRET'])

Install with Poetry

This is a sample project.toml file which you can use with poetry install to setup spark NLP + the Healthcare python library spark-nlp-jsl

You need to point it to either the tar.gz or .whl file which are hosted at https://pypi.johnsnowlabs.com/<SECRET>/spark-nlp-jsl/

NOTE You must update the url whenever you are upgrading your spark-nlp-jsl version

[tool.poetry]
name = "poertry_demo"
version = "0.1.0"
description = ""
authors = ["person <person@gmail.com>"]

[tool.poetry.dependencies]
python = "^3.7"

[tool.poetry.dev-dependencies]
spark-nlp = "3.4.4"
spark-nlp-jsl = { url = "https://pypi.johnsnowlabs.com/SECRET/spark-nlp-jsl/spark_nlp_jsl-tar.gz_OR_.whl" }

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

Spark-NLP for Healthcare in AWS EMR

In this page we explain how to setup Spark-NLP + Spark-NLP Healthcare in AWS EMR, using the AWS console.

Steps

  1. You must go to the blue button “Create Cluster” on the UI. By doing that you will get directed to the “Create Cluster - Quick Options” page. Don’t use the quick options, click on “Go to advanced options” instead.
  2. Now in Advanced Options, on Step 1, “Software and Steps”, please pick the following selection in the checkboxes, software config Also in the “Edit Software Settings” page, enter the following,
[{
  "Classification": "spark-env",
  "Configurations": [{
    "Classification": "export",
    "Properties": {
      "PYSPARK_python": "/usr/bin/python3",
      "AWS_ACCESS_KEY_ID": "XYXYXYXYXYXYXYXYXYXY",
      "AWS_SECRET_ACCESS_KEY": "XYXYXYXYXYXYXYXYXYXY", 
      "SPARK_NLP_LICENSE": "XYXYXYXYXYXYXYXYXYXYXYXYXYXY"
    }
  }]
},
{
  "Classification": "spark-defaults",
    "Properties": {
      "spark.yarn.stagingDir": "hdfs:///tmp",
      "spark.yarn.preserve.staging.files": "true",
      "spark.kryoserializer.buffer.max": "2000M",
      "spark.serializer": "org.apache.spark.serializer.KryoSerializer",
      "spark.driver.maxResultSize": "0",
      "spark.driver.memory": "32G"
    }
}]

Make sure that you replace all the secret information(marked here as XYXYXYXYXY) by the appropriate values that you received with your license.

  1. In “Step 2” choose the hardware and networking configuration you prefer, or just pick the defaults. Move to next step by clocking the “Next” blue button.
  2. Now you are in “Step 3”, in which you assign a name to your cluster, and you can change the location of the cluster logs. If the location of the logs is OK for you, take note of the path so you can debug potential problems by using the logs.
  3. Still on “Step 3”, go to the bottom of the page, and expand the “Bootstrap Actions” tab. We’re gonna add an action to execute during bootstrap of the cluster. Select “Custom Action”, then press on “Configure and add”.
    You need to provide a path to a script on S3. The path needs to be public. Keep this in mind, no secret information can be contained there.
    The script we’ll used for this setup is emr_bootstrap.sh .
    This script will install Spark-NLP 3.1.0, and Spark-NLP Healthcare 3.1.1. You’ll have to edit the script if you need different versions.
    After you entered the route to S3 in which you place the emr_bootstrap.sh file, and before clicking “add” in the dialog box, you must pass an additional parameter containing the SECRET value you received with your license. Just paste the secret on the “Optional arguments” field in that dialog box.
  4. There’s not much additional setup you need to perform. So just start a notebook server, connect it to the cluster you just created(be patient, it takes a while), and test with the NLP_EMR_Setup.ipynb test notebook.
