[Bug]: pip not in PATH in dstackai/efa image – causes exit status 127

[Bihan]

Steps to reproduce

1. Create task with the following configuration:

type: task
name: test-efa

image: dstackai/efa

commands:
  - pip install torch

resources:
  gpu: 1

2. Run the task

Actual behaviour

The task fails immediately with the following error:

Run failed with error code CONTAINER_EXITED_WITH_ERROR.
Exit status: 127.

This indicates that the pip command is not found in the container’s PATH.

Expected behaviour

1. pip should be available in the default PATH so that standard Python package installation commands work out of the box.

This was confirmed to be a PATH issue by adding the following to the task:

commands:
  - export PATH=/opt/conda/envs/workflow/bin:$PATH
  - pip install torch

This workaround succeeds, confirming the missing pip from PATH.

2. Include uv as the default Python package manager, consistent with other official dstack images.

I believe this should be fixed in #2799
