To use Spark NLP you need the following requirements:
- Java 8 and 11
- Apache Spark 3.5.x, 3.4.x, 3.3.x, 3.2.x, 3.1.x, 3.0.x
GPU (optional):
Spark NLP 5.2.3 is built with ONNX 1.16.3 and TensorFlow 2.7.1 deep learning engines. The minimum following NVIDIA® software are only required for GPU support:
- NVIDIA® GPU drivers version 450.80.02 or higher
- CUDA® Toolkit 11.2
- cuDNN SDK 8.1.0
This is a quick example of how to use Spark NLP pre-trained pipeline in Python and PySpark:
$ java -version
# should be Java 8 or 11 (Oracle or OpenJDK)
$ conda create -n sparknlp python=3.7 -y
$ conda activate sparknlp
# spark-nlp by default is based on pyspark 3.x
$ pip install spark-nlp==5.2.3 pyspark==3.3.1
In Python console or Jupyter Python3
kernel:
# Import Spark NLP
from sparknlp.base import *
from sparknlp.annotator import *
from sparknlp.pretrained import PretrainedPipeline
import sparknlp
# Start SparkSession with Spark NLP
# start() functions has 3 parameters: gpu, apple_silicon, and memory
# sparknlp.start(gpu=True) will start the session with GPU support
# sparknlp.start(apple_silicon=True) will start the session with macOS M1 & M2 support
# sparknlp.start(memory="16G") to change the default driver memory in SparkSession
spark = sparknlp.start()
# Download a pre-trained pipeline
pipeline = PretrainedPipeline('explain_document_dl', lang='en')
# Your testing dataset
text = """
The Mona Lisa is a 16th century oil painting created by Leonardo.
It's held at the Louvre in Paris.
"""
# Annotate your testing dataset
result = pipeline.annotate(text)
# What's in the pipeline
list(result.keys())
Output: ['entities', 'stem', 'checked', 'lemma', 'document',
'pos', 'token', 'ner', 'embeddings', 'sentence']
# Check the results
result['entities']
Output: ['Mona Lisa', 'Leonardo', 'Louvre', 'Paris']

Spark NLP supports Python 3.6.x and above depending on your major PySpark version.
If you installed pyspark through pip/conda, you can install spark-nlp
through the same channel.
Pip:
pip install spark-nlp==5.2.3
Conda:
conda install -c johnsnowlabs spark-nlp
PyPI spark-nlp package / Anaconda spark-nlp package
Then you'll have to create a SparkSession either from Spark NLP:
import sparknlp
spark = sparknlp.start()
or manually:
spark = SparkSession.builder
.appName("Spark NLP")
.master("local[*]")
.config("spark.driver.memory", "16G")
.config("spark.driver.maxResultSize", "0")
.config("spark.kryoserializer.buffer.max", "2000M")
.config("spark.jars.packages", "com.johnsnowlabs.nlp:spark-nlp_2.12:5.2.3")
.getOrCreate()
If using local jars, you can use spark.jars
instead for comma-delimited jar files. For cluster setups, of course,
you'll have to put the jars in a reachable location for all driver and executor nodes.
Quick example:
import sparknlp
from sparknlp.pretrained import PretrainedPipeline
# create or get Spark Session
spark = sparknlp.start()
sparknlp.version()
spark.version
# download, load and annotate a text by pre-trained pipeline
pipeline = PretrainedPipeline('recognize_entities_dl', 'en')
result = pipeline.annotate('The Mona Lisa is a 16th century oil painting created by Leonardo')
- FAT-JAR for CPU on Apache Spark 3.0.x, 3.1.x, 3.2.x, 3.3.x, 3.4.x, and 3.5.x
sbt assembly
- FAT-JAR for GPU on Apache Spark 3.0.x, 3.1.x, 3.2.x, 3.3.x, 3.4.x, and 3.5.x
sbt -Dis_gpu=true assembly
- FAT-JAR for M! on Apache Spark 3.0.x, 3.1.x, 3.2.x, 3.3.x, 3.4.x, and 3.5.x
sbt -Dis_silicon=true assembly
If for some reason you need to use the JAR, you can either download the Fat JARs provided here or download it from Maven Central.
To add JARs to spark programs use the --jars
option:
spark-shell --jars spark-nlp.jar
The preferred way to use the library when running spark programs is using the --packages
option as specified in
the spark-packages
section.
Use either one of the following options
- Add the following Maven Coordinates to the interpreter's library list
com.johnsnowlabs.nlp:spark-nlp_2.12:5.2.3
- Add a path to pre-built jar from here in the interpreter's library list making sure the jar is available to driver path
Apart from the previous step, install the python module through pip
pip install spark-nlp==5.2.3
Or you can install spark-nlp
from inside Zeppelin by using Conda:
python.conda install -c johnsnowlabs spark-nlp
Configure Zeppelin properly, use cells with %spark.pyspark or any interpreter name you chose.
Finally, in Zeppelin interpreter settings, make sure you set properly zeppelin.python to the python you want to use and
install the pip library with (e.g. python3
).
An alternative option would be to set SPARK_SUBMIT_OPTIONS
(zeppelin-env.sh) and make sure --packages
is there as
shown earlier since it includes both scala and python side installation.
Recommended:
The easiest way to get this done on Linux and macOS is to simply install spark-nlp
and pyspark
PyPI packages and
launch the Jupyter from the same Python environment:
$ conda create -n sparknlp python=3.8 -y
$ conda activate sparknlp
# spark-nlp by default is based on pyspark 3.x
$ pip install spark-nlp==5.2.3 pyspark==3.3.1 jupyter
$ jupyter notebook
Then you can use python3
kernel to run your code with creating SparkSession via spark = sparknlp.start()
.
Optional:
If you are in different operating systems and require to make Jupyter Notebook run by using pyspark, you can follow these steps:
export SPARK_HOME=/path/to/your/spark/folder
export PYSPARK_PYTHON=python3
export PYSPARK_DRIVER_PYTHON=jupyter
export PYSPARK_DRIVER_PYTHON_OPTS=notebook
pyspark --packages com.johnsnowlabs.nlp:spark-nlp_2.12:5.2.3
Alternatively, you can mix in using --jars
option for pyspark + pip install spark-nlp
If not using pyspark at all, you'll have to run the instructions pointed here
Google Colab is perhaps the easiest way to get started with spark-nlp. It requires no installation or setup other than having a Google account.
Run the following code in Google Colab notebook and start using spark-nlp right away.
# This is only to setup PySpark and Spark NLP on Colab
!wget https://setup.johnsnowlabs.com/colab.sh -O - | bash
This script comes with the two options to define pyspark
and spark-nlp
versions via options:
# -p is for pyspark
# -s is for spark-nlp
# -g will enable upgrading libcudnn8 to 8.1.0 on Google Colab for GPU usage
# by default they are set to the latest
!wget https://setup.johnsnowlabs.com/colab.sh -O - | bash /dev/stdin -p 3.2.3 -s 5.2.3
Spark NLP quick start on Google Colab is a live demo on Google Colab that performs named entity recognitions and sentiment analysis by using Spark NLP pretrained pipelines.
Run the following code in Kaggle Kernel and start using spark-nlp right away.
# Let's setup Kaggle for Spark NLP and PySpark
!wget https://setup.johnsnowlabs.com/kaggle.sh -O - | bash
This script comes with the two options to define pyspark
and spark-nlp
versions via options:
# -p is for pyspark
# -s is for spark-nlp
# -g will enable upgrading libcudnn8 to 8.1.0 on Kaggle for GPU usage
# by default they are set to the latest
!wget https://setup.johnsnowlabs.com/colab.sh -O - | bash /dev/stdin -p 3.2.3 -s 5.2.3

Create a cluster if you don't have one already
-
On a new cluster or existing one you need to add the following to the
Advanced Options -> Spark
tab:spark.kryoserializer.buffer.max 2000M spark.serializer org.apache.spark.serializer.KryoSerializer
-
In
Libraries
tab inside your cluster you need to follow these steps:3.1. Install New -> PyPI ->
spark-nlp==5.2.3
-> Install3.2. Install New -> Maven -> Coordinates ->
com.johnsnowlabs.nlp:spark-nlp_2.12:5.2.3
-> Install -
Now you can attach your notebook to the cluster and use Spark NLP!
NOTE: Databricks' runtimes support different Apache Spark major releases. Please make sure you choose the correct Spark NLP Maven package name (Maven Coordinate) for your runtime from our Packages Cheatsheet
To launch EMR clusters with Apache Spark/PySpark and Spark NLP correctly you need to have bootstrap and software configuration.

If you use the previous image-version from 2.0, you should also add ANACONDA to optional-components. And, you should enable gateway. Don't forget to set the maven coordinates for the jar in properties.

-
On an existing one, you need to install spark-nlp and spark-nlp-display packages from PyPI.
-
Now, you can attach your notebook to the cluster and use the Spark NLP!
You can change the following Spark NLP configurations via Spark Configuration:
Property Name | Default | Meaning |

SparkSession:
You can use .config()
during SparkSession creation to set Spark NLP configurations.
from pyspark.sql import SparkSession
spark = SparkSession.builder
.master("local[*]")
.config("spark.driver.memory", "16G")
.config("spark.driver.maxResultSize", "0")
.config("spark.serializer", "org.apache.spark.serializer.KryoSerializer")

--conf spark.jsl.settings.storage.cluster_tmp_dir="sample_data/storage" \
--packages com.johnsnowlabs.nlp:spark-nlp_2.12:5.2.3
Databricks:
On a new cluster or existing one you need to add the following to the Advanced Options -> Spark
tab:
spark.kryoserializer.buffer.max 2000M
spark.serializer org.apache.spark.serializer.KryoSerializer
spark.jsl.settings.pretrained.cache_folder dbfs:/PATH_TO_CACHE
spark.jsl.settings.storage.cluster_tmp_dir dbfs:/PATH_TO_STORAGE
spark.jsl.settings.annotator.log_folder dbfs:/PATH_TO_LOGS
NOTE: If this is an existing cluster, after adding new configs or changing existing properties you need to restart it.
In Spark NLP we can define S3 locations to:
- Export log files of training models
- Store tensorflow graphs used in
NerDLApproach
Logging:
To configure S3 path for logging while training models. We need to set up AWS credentials as well as an S3 path
spark.conf.set("spark.jsl.settings.annotator.log_folder", "s3:https://my/s3/path/logs")
spark.conf.set("spark.jsl.settings.aws.credentials.access_key_id", "MY_KEY_ID")
spark.conf.set("spark.jsl.settings.aws.credentials.secret_access_key", "MY_SECRET_ACCESS_KEY")
spark.conf.set("spark.jsl.settings.aws.s3_bucket", "my.bucket")
spark.conf.set("spark.jsl.settings.aws.region", "my-region")
Now you can check the log on your S3 path defined in spark.jsl.settings.annotator.log_folder property. Make sure to use the prefix s3:https://, otherwise it will use the default configuration.
Tensorflow Graphs:
To reference S3 location for downloading graphs. We need to set up AWS credentials
spark.conf.set("spark.jsl.settings.aws.credentials.access_key_id", "MY_KEY_ID")
spark.conf.set("spark.jsl.settings.aws.credentials.secret_access_key", "MY_SECRET_ACCESS_KEY")
spark.conf.set("spark.jsl.settings.aws.region", "my-region")
MFA Configuration:
In case your AWS account is configured with MFA. You will need first to get temporal credentials and add session token to the configuration as shown in the examples below For logging:
spark.conf.set("spark.jsl.settings.aws.credentials.session_token", "MY_TOKEN")
An example of a bash script that gets temporal AWS credentials can be found here This script requires three arguments:
./aws_tmp_credentials.sh iam_user duration serial_number
Quick example:
import com.johnsnowlabs.nlp.pretrained.PretrainedPipeline
import com.johnsnowlabs.nlp.SparkNLP
SparkNLP.version()
val testData = spark.createDataFrame(Seq(
(1, "Google has announced the release of a beta version of the popular TensorFlow machine learning library"),

Spark NLP library and all the pre-trained models/pipelines can be used entirely offline with no access to the Internet. If you are behind a proxy or a firewall with no access to the Maven repository (to download packages) or/and no access to S3 (to automatically download models and pipelines), you can simply follow the instructions to have Spark NLP without any limitations offline:
- Instead of using the Maven package, you need to load our Fat JAR
- Instead of using PretrainedPipeline for pretrained pipelines or the
.pretrained()
function to download pretrained models, you will need to manually download your pipeline/model from Models Hub, extract it, and load it.
Example of SparkSession
with Fat JAR to have Spark NLP offline:
spark = SparkSession.builder
.appName("Spark NLP")
.master("local[*]")
.config("spark.driver.memory", "16G")
.config("spark.driver.maxResultSize", "0")
.config("spark.kryoserializer.buffer.max", "2000M")
.config("spark.jars", "/tmp/spark-nlp-assembly-5.2.3.jar")
.getOrCreate()
- You can download provided Fat JARs from each release notes, please pay attention to pick the one that suits your environment depending on the device (CPU/GPU) and Apache Spark version (3.0.x, 3.1.x, 3.2.x, 3.3.x, 3.4.x, and 3.5.x)
- If you are local, you can load the Fat JAR from your local FileSystem, however, if you are in a cluster setup you need
to put the Fat JAR on a distributed FileSystem such as HDFS, DBFS, S3, etc. (
i.e.,
hdfs:https:///tmp/spark-nlp-assembly-5.2.3.jar
)
Example of using pretrained Models and Pipelines in offline:
# instead of using pretrained() for online:
# french_pos = PerceptronModel.pretrained("pos_ud_gsd", lang="fr")
# you download this model, extract it, and use .load
french_pos = PerceptronModel.load("/tmp/pos_ud_gsd_fr_2.0.2_2.4_1556531457346/")
.setInputCols("document", "token")
.setOutputCol("pos")
# example for pipelines
# instead of using PretrainedPipeline
# pipeline = PretrainedPipeline('explain_document_dl', lang='en')
# you download this pipeline, extract it, and use PipelineModel
PipelineModel.load("/tmp/explain_document_dl_en_2.0.2_2.4_1556530585689/")
- Since you are downloading and loading models/pipelines manually, this means Spark NLP is not downloading the most recent and compatible models/pipelines for you. Choosing the right model/pipeline is on you
- If you are local, you can load the model/pipeline from your local FileSystem, however, if you are in a cluster setup
you need to put the model/pipeline on a distributed FileSystem such as HDFS, DBFS, S3, etc. (
i.e.,
hdfs:https:///tmp/explain_document_dl_en_2.0.2_2.4_1556530585689/
)
