Automatic Dependency Installation

· 3 min read

proxiML jobs now accept lists of packages that will be installed using apt, pip, or conda as part of the job creation process and will automatically install dependencies found in the requirements.txt file in the root of the model code working directory.

How It Works​

You can now specify a list of apt, pip, and/or conda packages as part of the job creation process. After the job's model code is loaded, proxiML will automatically install the packages from the apt list, the conda list, the requirements.txt file, and finally the pip list. Specifying package dependencies works for all job types and is particularly recommended for non-notebook jobs.

Using the Web Platform​

Navigate to the dashboard of whichever job type you wish to create and click the Create button. After filling out the other fields necessary to start the job, expand the Environment section of the form. There are now 3 new text areas under the Package Dependencies header for the pip, apt, and conda dependency lists, respectively. Each package should be added on its own line. If you need to pin a specific version of the dependency, use the same syntax you would when running the package manager's install command, e.g. package==version for pip, package=version for apt, and "package=version" for conda. Click Next and review the list of packages to install and create the job.

No additional configuration is necessary to install the pip requirements.txt file. Simply insure the file is well formatted and in the root directory of the model you specify in the Model section of the job form.

Using the SDK​

To specify package dependencies using the SDK, add a packages dictionary to the environment dictionary of the job create command. The packages dictionary only allows the three keys (apt,pip, and conda) to be specified, but none of the keys are required. The package dependencies should be specified as lists of strings. When pinning conda packages, be sure to include the quotes explicitly. An example specification is the following:


job = await proximl.jobs.create(
    name="Test Notebook Job",
    ...
    environment=dict(
        type="DEEPLEARNING_PY38",
        packages=dict(
            apt=["llvm-9-dev", "libpng-dev"],
            pip=["fbprophet", "catboost", "nemo_toolkit[all]==1.0.0b2"],
            conda=["libuv", "libpng", ""pyarrow=3.0.0""],
        ),
    ),
)

Using the CLI​

To specify package dependencies using the CLI, use the command line option for the package manager you need (apt-packages, pip-packages, or conda-packages). Packages should be specified as single CSV argument. An example is the following:

proximl job create notebook \
 --apt-packages 'llvm-9-dev,libpng-dev' \
 --pip-packages 'fbprophet,catboost,nemo_toolkit[all]==1.0.0b2' \
 --conda-packages 'libuv,libpng,"pyarrow=3.0.0"' \
 "Test Notebook Job"
