Pip queue environment for Deadline Cloud

The pip_queue_env.yaml queue environment provides Python packages to jobs using pip and the standard library venv module, rather than a package manager such as conda or Rez.

When a job provides a PipPackages parameter value, the queue environment creates a Python virtual environment in the session working directory, installs the requested packages into it with pip, and activates it so that the job's steps run with those packages available. If PipPackages is empty, the queue environment does nothing, so you can add it to a queue that also runs jobs that don't use it.

The PipIndexUrl and PipExtraIndexUrls parameters let jobs install from a private package index, such as an AWS CodeArtifact repository, instead of the default PyPI index.

Unlike conda and Rez, pip and venv are included with Python itself, so worker hosts only need a python3 (or python) interpreter on the PATH. Deadline Cloud service-managed fleets provide one.

The pip_package_job job bundle shows how to submit a job that uses this queue environment. For a job bundle that defines the same pip environment inline without a queue environment, see pip_self_contained_job.
