trains-agent doesn't run the clone, it is pip...
basically calling "pip install git+https://..."
Not sure you can pass extra arguments
Also, this is not a setup problem, otherwise it would have seen consistently failing ... this actually looks like a network issue.
The only thing I can think of is retrying to install if we get network error (not sure whats the exit code of pip though (maybe 9?)

mmmmh I just restarted the experiment and it seems to work now. I am not sure why that happened. From this SO it could be related to size of the repo. Might be a good idea to clone with --depth 1 in the agents?
Or more generally, try to catch this error and retry a few times?

Unfortunately this is difficult to reproduce... Neverthless it would be important to me to be robust against it, because if this error happens in a task in the middle of my pipeline, the whole process fails.

This binds to another wider topic I think: How to "skip" tasks if they already run (a mechanism similar to what [ https://luigi.readthedocs.io/en/stable/ ] offers). That would allow to restart the pipeline and skip tasks until the point where the task failed

Hi JitteryCoyote63 ,
I remember seeing something similar on our GitHub...
The error itself is pip failing to run "git clone" , seems like a weird network connection error (TLS is the HTTPS security layer)
