I’ve got a 
pants-jupyter-plugin
 related question. I am using
pants-jupyter-plugin
  in AWS SageMaker Studio. I have a failure with
%pants_load
, but there is little information in the error log and I am struggling to investigate.

There are many dependent libraries and it takes a long time to install them, so I’m guessing that’s the cause.
https://github.com/pantsbuild/pants-jupyter-plugin/blob/main/pants_jupyter_plugin/pex.py#L131-L149 There doesn’t seem to be a timeout setting, so that guess may be wrong.

@bland-father-19717 can you try running the PEX directly to see if that reveal more? Basically just run the exact command shown as failing:
Copy code
!/usr/local/bin/python /root/.cache/pants_jupyter_plugin/pex/exes/pex-2.1.56.pex -m pex.tools /root/xxx-experimental/dist/tmpammo36v6/src.python.lib.xxx/pex_binary.pex venv /root/.cache/pants_jupyter_plugin/pex/venvs/e64be65ccbc3df/pex_binary.pex.test
Here I just changed the original
/root/.cache/pants_jupyter_plugin/pex/venvs/e64be65ccbc3df/pex_binary.pex.80bcffde
to `/root/.cache/pants_jupyter_plugin/pex/venvs/e64be65ccbc3df/pex_binary.pex.test`in case that original venv target directory was created as part of the error.

My apologies. I missed one important detail! You need to export PEX_TOOLS=1, so?:
Copy code

I'm not sure exactly how
!
works in a notebook though. That example uses a bash / shell-ism with the
ENV_VAR=VALUE ...rest
structure. There may be some other way you need to do this in a notebook.
Oh wait - sorry again, that's not it.
Just a minute...
👌 1
Copy code
!PEX_INTERPRETER=1 PEX_PYTHON_PATH=/usr/local/bin/python /usr/local/bin/python /root/.cache/pants_jupyter_plugin/pex/exes/pex-2.1.56.pex -m pex.tools /root/xxx-experimental/dist/tmpammo36v6/src.python.lib.xxx/pex_binary.pex venv /root/.cache/pants_jupyter_plugin/pex/venvs/e64be65ccbc3df/pex_binary.pex.test
That's exactly the environment + command being run.

Hrm.
So the PEX_TOOLS=1 ... venv command does support saying
--collisions-ok
but the pants-jupyter-plugin doesn't currently pass this. Thinking what's best to do here...
@bland-father-19717 so in your case is that binary unused / irrelevant?
bin/tensorboard
?

No, the collision here is purely inside the PEX. If you look at those two paths, one instance is provided by
tensorflow-2.4.1-cp38-cp38-manylinux2010_x86_64.whl/bin/tensorboard
and one by
tensorboard-2.8.0-py3-none-any.whl/bin/tensorboard
. Pex doesn't care about the 3rd
/usr/local/bin/tensorboard
instance you point out.
The fact that tensorflow and tensorboard both use the same binary name
tensorboard
is generally problematic!
OK, let me see what I can think up. I'll start with an issue. It may be that just saying
--collisions-ok
is the way to go. IIRC that still issues a warning; so you won't be totally blind in the notebook when the collision later turns out to be important (if it does).

I have never seen an OSS that goes from question to release so quickly. Thank you for your support.
