Getting Started with Morpheus

There are three ways to get started with Morpheus:

The pre-built Docker containers are the easiest way to get started with the latest release of Morpheus. Released versions of Morpheus containers can be found on NGC.

More advanced users, or those who are interested in using the latest pre-release features, will need to build the Morpheus container or build from source.

Requirements

Note about Docker:

The Morpheus documentation and examples assume that the Manage Docker as a non-root user post install step has been performed allowing Docker commands to be executed by a non-root user. This is not strictly necessary so long as the current user has sudo privileges to execute Docker commands.

Using pre-built Docker containers

Pull the Morpheus Image

  1. Go to https://catalog.ngc.nvidia.com/orgs/nvidia/teams/morpheus/containers/morpheus/tags
  2. Choose a version
  3. Download the selected version, for example for 23.01:
docker pull nvcr.io/nvidia/morpheus/morpheus:23.01-runtime

Note about Morpheus versions:

Morpheus uses Calendar Versioning (CalVer). For each Morpheus release there will be an image tagged in the form of YY.MM-runtime this tag will always refer to the latest point release for that version. In addition to this there will also be at least one point release version tagged in the form of vYY.MM.00-runtime this will be the initial point release for that version (ex. v23.01.00-runtime). In the event of a major bug, we may release additional point releases (ex. v23.01.01-runtime, v23.01.02-runtime etc...), and the YY.MM-runtime tag will be updated to reference that point release.

Users who want to ensure they are running with the latest bug fixes should use a release image tag (YY.MM-runtime). Users who need to deploy a specific version into production should use a point release image tag (vYY.MM.00-runtime).

Starting the Morpheus Container

  1. Ensure that The NVIDIA Container Toolkit is installed.
  2. Start the container downloaded from the previous section:
docker run --rm -ti --runtime=nvidia --gpus=all --net=host -v /var/run/docker.sock:/var/run/docker.sock nvcr.io/nvidia/morpheus/morpheus:23.01-runtime bash

Note about some of the flags above:

Flag Description
--runtime=nvidia Choose the NVIDIA docker runtime, this enables access to the GPU inside the container. This flag isn't needed if the nvidia runtime is already set as the default runtime for Docker.
--gpus=all Specify which GPUs the container has access to. Alternately a specific GPU could be chosen with --gpus=<gpu-id>
--net=host Most of the Morpheus pipelines utilize NVIDIA Triton Inference Server, which will be running in another container. For simplicity we will give the container access to the host system's network, production deployments may opt for an explicit network configuration.
-v /var/run/docker.sock:/var/run/docker.sock Enables access to the Docker socket file from within the running container, this allows launching other Docker containers from within the Morpheus container. This flag is required for launching Triton with access to the included Morpheus models, users with their own models can omit this.

Once launched, users wishing to launch Triton using the included Morpheus models will need to install the Docker tools in the Morpheus container by running:

./external/utilities/docker/install_docker.sh

Skip ahead to the Launching Triton Server section.

Building the Morpheus Container

Clone the Repository

MORPHEUS_ROOT=$(pwd)/morpheus
git clone https://github.com/nv-morpheus/Morpheus.git $MORPHEUS_ROOT
cd $MORPHEUS_ROOT

Git LFS

The large model and data files in this repo are stored using Git Large File Storage (LFS). Only those files which are strictly needed to run Morpheus are downloaded by default when the repository is cloned.

The scripts/fetch_data.py script can be used to fetch the Morpheus pre-trained models, and other files required for running the training/validation scripts and example pipelines.

Usage of the script is as follows:

scripts/fetch_data.py fetch <dataset> [<dataset>...]

At time of writing the defined datasets are:

  • all - Metaset includes all others
  • docs - Graphics needed for documentation
  • examples - Data needed by scripts in the examples subdir
  • models - Morpheus models (largest dataset)
  • tests - Data used by unittests
  • validation - Subset of the models dataset needed by some unittests

To download just the examples and models:

scripts/fetch_data.py fetch examples models

To download the data needed for unittests:

scripts/fetch_data.py fetch tests validation

If Git LFS is not installed before cloning the repository, the scripts/fetch_data.py script will fail. If this is the case, follow the instructions for installing Git LFS from here, and then run the following command:

git lfs install

Build the Container

To assist in building the Morpheus container, several scripts have been provided in the ./docker directory. To build the "release" container, run the following:

./docker/build_container_release.sh

By default this will create an image named nvcr.io/nvidia/morpheus/morpheus:${MORPHEUS_VERSION}-runtime where $MORPHEUS_VERSION is replaced by the output of git describe --tags --abbrev=0. You can specify a different Docker image name and tag by passing the script the DOCKER_IMAGE_NAME, and DOCKER_IMAGE_TAG environment variables respectively.

To run the built "release" container, use the following:

./docker/run_container_release.sh

The ./docker/run_container_release.sh script accepts the same DOCKER_IMAGE_NAME, and DOCKER_IMAGE_TAG environment variables that the ./docker/build_container_release.sh script does. For example, to run version v23.01.00a use the following:

DOCKER_IMAGE_TAG="v23.01.00a-runtime" ./docker/run_container_release.sh

Launching Triton Server

Many of the validation tests and example workflows require a Triton server to function. In a new terminal, from the root of the Morpheus repo, use the following command to launch a Docker container for Triton loading all of the included pre-trained models:

docker run --rm -ti --gpus=all -p8000:8000 -p8001:8001 -p8002:8002 \
  -v $PWD/models:/models \
  nvcr.io/nvidia/tritonserver:22.08-py3 \
  tritonserver --model-repository=/models/triton-model-repo \
    --exit-on-error=false \
    --log-info=true \
    --strict-readiness=false \
    --disable-auto-complete-config

This will launch Triton using the default network ports (8000 for HTTP, 8001 for GRPC, and 8002 for metrics), loading all of the examples models in the Morpheus repo.

Note: The above command is useful for testing out Morpheus, however it does load several models into GPU memory, which at time of writing consumes roughly 2GB of GPU memory. Production users should consider only loading the specific model(s) they plan on using with the --model-control-mode=explicit and --load-model flags. For example to launch Triton only loading the abp-nvsmi-xgb model:

docker run --rm -ti --gpus=all -p8000:8000 -p8001:8001 -p8002:8002 \
  -v $PWD/models:/models \
  nvcr.io/nvidia/tritonserver:22.08-py3 \
  tritonserver --model-repository=/models/triton-model-repo \
    --exit-on-error=false \
    --log-info=true \
    --strict-readiness=false \
    --disable-auto-complete-config \
    --model-control-mode=explicit \
    --load-model abp-nvsmi-xgb

Running Morpheus

To run Morpheus, users will need to choose from the Morpheus Command Line Interface (CLI) or Python interface. Which interface to use depends on the user's needs, amount of customization, and operating environment. More information on each interface can be found below.

For full example pipelines using both the Python API and command line interface, refer to the Morpheus Examples.

Morpheus Python Interface

The Morpheus Python interface allows users to configure their pipelines using a Python script file. This is ideal for users who are working in a Jupyter Notebook, and users who need complex initialization logic. Documentation on using both the Morpheus Python & C++ APIs can be found in the Morpheus Developer Guide.

Morpheus Command Line Interface (CLI)

The CLI allows users to completely configure a Morpheus pipeline directly from a terminal. This is ideal for users configuring a pipeline in Kubernetes. The Morpheus CLI can be invoked using the morpheus command and is capable of running linear pipelines as well as additional tools. Instructions for using the CLI can be queried directly in the terminal using morpheus --help:

$ morpheus --help
Usage: morpheus [OPTIONS] COMMAND [ARGS]...

Options:
  --debug / --no-debug            [default: no-debug]
  --log_level [CRITICAL|FATAL|ERROR|WARN|WARNING|INFO|DEBUG]
                                  Specify the logging level to use.  [default:
                                  WARNING]
  --log_config_file FILE          Config file to use to configure logging. Use
                                  only for advanced situations. Can accept
                                  both JSON and ini style configurations
  --plugin TEXT                   Adds a Morpheus CLI plugin. Can either be a
                                  module name or path to a python module
  --version                       Show the version and exit.
  --help                          Show this message and exit.

Commands:
  run    Run one of the available pipelines
  tools  Run a utility tool

Each command in the CLI has its own help information. Use morpheus [command] [...sub-command] --help to get instructions for each command and sub command. For example:

$ morpheus run pipeline-nlp inf-triton --help
Configuring Pipeline via CLI
Usage: morpheus run pipeline-nlp inf-triton [OPTIONS]

Options:
  --model_name TEXT               Model name in Triton to send messages to
                                  [required]
  --server_url TEXT               Triton server URL (IP:Port)  [required]
  --force_convert_inputs BOOLEAN  Instructs this stage to forcibly convert all
                                  input types to match what Triton is
                                  expecting. Even if this is set to `False`,
                                  automatic conversion will be done only if
                                  there would be no data loss (i.e. int32 ->
                                  int64).  [default: False]
  --use_shared_memory BOOLEAN     Whether or not to use CUDA Shared IPC Memory
                                  for transferring data to Triton. Using CUDA
                                  IPC reduces network transfer time but
                                  requires that Morpheus and Triton are
                                  located on the same machine  [default:
                                  False]
  --help                          Show this message and exit.  [default:
                                  False]

Several examples on using the Morpheus CLI can be found in the Basic Usage guide along with the other Morpheus Examples.

CLI Stage Configuration

When configuring a pipeline via the CLI, you start with the command morpheus run pipeline and then list the stages in order from start to finish. The order that the commands are placed in will be the order that data flows from start to end. The output of each stage will be linked to the input of the next. For example, to build a simple pipeline that reads from Kafka, deserializes messages, serializes them, and then writes to a file, use the following:

morpheus --log_level=INFO run pipeline-nlp from-kafka --bootstrap_servers localhost:9092 --input_topic test_pcap deserialize serialize to-file --filename .tmp/temp_out.json --overwrite

The output should contain lines similar to:

====Pipeline Started====
Added source: <from-kafka-0; KafkaSourceStage(bootstrap_servers=localhost:9092, input_topic=test_pcap, group_id=morpheus, client_id=None, poll_interval=10millis, disable_commit=False, disable_pre_filtering=False, auto_offset_reset=AutoOffsetReset.LATEST, stop_after=0, async_commits=True)>
  └─> morpheus.MessageMeta
Added stage: <deserialize-1; DeserializeStage()>
  └─ morpheus.MessageMeta -> morpheus.MultiMessage
Added stage: <serialize-2; SerializeStage(include=(), exclude=('^ID$', '^_ts_'), fixed_columns=True)>
  └─ morpheus.MultiMessage -> morpheus.MessageMeta
Added stage: <to-file-3; WriteToFileStage(filename=.tmp/temp_out.json, overwrite=False, file_type=FileTypes.Auto, include_index_col=True)>
  └─ morpheus.MessageMeta -> morpheus.MessageMeta

This is important because, when the log level is set to INFO and above, it shows you the order of the stages and the output type of each one. Since some stages cannot accept all types of inputs, Morpheus will report an error if you have configured your pipeline incorrectly. For example, if we run the same command as above but forget the serialize stage, Morpheus should output an error similar to:

$ morpheus run pipeline-nlp from-kafka --bootstrap_servers localhost:9092 --input_topic test_pcap deserialize to-file --filename .tmp/temp_out.json --overwrite
Configuring Pipeline via CLI
Starting pipeline via CLI... Ctrl+C to Quit
E20221214 14:53:17.425515 452045 controller.cpp:62] exception caught while performing update - this is fatal - issuing kill
E20221214 14:53:17.425714 452045 context.cpp:125] rank: 0; size: 1; tid: 140065439217216; fid: 0x7f6144041000: set_exception issued; issuing kill to current runnable. Exception msg: RuntimeError: The to-file stage cannot handle input of <class 'morpheus.messages.multi_message.MultiMessage'>. Accepted input types: (<class 'morpheus.messages.message_meta.MessageMeta'>,)

This indicates that the to-file stage cannot accept the input type of morpheus.pipeline.messages.MultiMessage. This is because the to-file stage has no idea how to write that class to a file; it only knows how to write messages of type morpheus.messages.message_meta.MessageMeta. To ensure you have a valid pipeline, examine at the Accepted input types: (<class 'morpheus.messages.message_meta.MessageMeta'>,) portion of the error message. This indicates you need a stage that converts from the output type of the deserialize stage, morpheus.pipeline.messages.MultiMessage, to morpheus.messages.message_meta.MessageMeta, which is exactly what the serialize stage does.
