We had issues like this one the last couple of days with some data-science libraries in our CI. It seems to me like this might be due to network related issues. Does this issue persist with new tries?
b
It does
s
Oh wait, it says 
pex
is not installed 🤔
w
@bitter-ability-32190: i think that this might be https://github.com/pantsbuild/pex/issues/1386 …?
is this a macOS machine (or did they otherwise change symlinks to python installs?)
b
Ubuntu 20
I doubt they changed any symlinks. Whats the easiest way to detect?
w
@bitter-ability-32190: to unblock them, could you have them stash the PEX root? i.e., move 
~/.cache/pants/named_caches/pex_root
somewhere else?
👀 1
the way to detect is to look for a mismatch between the Python that is failing to find something, and the site-packages directory of the virtualenv the error is occurring in (
.cache/pants/named_caches/pex_root/venvs/s/ec58be6e/venv/lib/python3.8/site-packages
in one case here). the idea being that the venv has been created for a different python than it is being used with (?)
so, if 3.7 or 3.9 was being used with a 3.8 venv
b
I'll tell them to wipe cache and try again. Will report back tomorrow with outcome
Wiping the cache doesn't fix the issue
w
hm, sorry… false alarm on https://github.com/pantsbuild/pex/issues/1386 then most likely. which version of Pants is this? the next step is most likely to use https://www.pantsbuild.org/v2.10/docs/troubleshooting#debug-tip-inspect-the-sandbox-with---no-process-cleanup to get access to the created sandbox, and then begin making modifications to the support scripts to get more nearby details.
i.e., assuming it fails with 
__run.sh
in the sandbox, inspect which virtualenv is being used, and then inspect the contents of the virtualenv to see why 
pex
might not be located.
or, if you jump straight to looking at the venv from the error message, trying to determine whether the 
site-packages
in that venv actually do contain 
pex
b
Hmm good suggestions
w
very sorry for the trouble. definitely interested in tracking these down… the pex mutable (“named”) cache is a deal with the devil to reduce the overhead of tracking many thousands of loose files.
😈 1
b
or, if you jump straight to looking at the venv from the error message, trying to determine whether the 
site-packages
in that venv actually do contain 
pex
Yeah the venv contains 
__pex_patched_pip__.py
but not 
pex
itself
w
so you repro the issue with 
__run.sh
…? can start adding debug output from there.
b
Yup!
Not sure where to start debugging though
w
the scripts inside the sandbox should be causing a venv to be created (or, if it already exists, to be reused) and then activated
…from a PEX located within the sandbox
so, one thing to maybe check is whether the PEX in the sandbox is itself valid: if it is valid, then the “venv creation or reuse” step is probably to blame
if it is not valid, then would need to back up a step to see where the invalid/partial PEX came from.
zipapp PEXes are just zip files (which in this case should contain 
pex
itself: a PEX of 
pex
), but they also contain a PEX-INFO file with more info.
b
How would I check validity?
w
see whether the PEX contains 
pex
and perhaps also just checking whether you can run it.
b
<path>python3.8 ./pex --help
works
w
ok. so that would point to the creation of the 
venv
from the PEX maybe being the issue.
b
./<path>/python3.8 ./pex audioread==2.1.8 --output-file foo
works as well
w
take a look inside the 
__run.sh
script to get a better idea of what this process is actually doing
b
Yeah, I'm gonna keep tacking on args until it fails
(sorry we get to play telephone 🙈 )
w
yea… unfortunately because this is probably Python-install specific, it’s probably not terribly portable.
b
As soon as I tack on 
--requirement requirements.txt
is when the 💥 happens
OK so small update, using the similar ish command as 
__runs.sh
to install just 
pycairo
has an error (that isn't the 
pex
one) where 
setup.py
runs 
pkg-config --print-errors --exists cairo>=1.15.10
and errors if there's output. This command has no output on my machine but does have output on the afflicted machine. So it might be an issue with the machine's setup as opposed to Pants. Both of our system have the same version of 
libcairo2-dev
installed though. So a possible lead, or a possible red-herring
h
Any updates on this?
b
pycairo
is installable outside of the sandbox. Thats about the only update 😞
Annnd now it isn't installable. 🎉 Pants is 100% a red herring
h
That sounds, ahem, fishy...
👀 1
b
I think something changed on the system that makes the library unbuildable from source. The prior litmus installation test was likely using a cached package
h
I was just making a "red herring" joke 😉

I apologise for resurrecting an old thread but observing the same error across multiple VMs. More details below. Unfortunately, I don't know how to reproduce the issue 😕 The error shown originally is this one:

That wasn't the only lib that was failing. After commenting out broken deps, this is the list that I came up with: • 
fire==0.5.0 ; python_version >= "3.9" and python_version < "4.0"
• 
flask-testing==0.8.1 ; python_version >= "3.9" and python_version < "4.0"
• 
memory-profiler==0.58.0 ; python_version >= "3.9" and python_version < "4.0"
• 
mypy-extensions==0.4.4 ; python_version >= "3.9" and python_version < "4.0"
• 
pyrepl==0.9.0 ; python_version >= "3.9" and python_version < "4.0"
• 
python-constraint==1.4.0 ; python_version >= "3.9" and python_version < "4.0"
• 
starkbank-ecdsa==2.2.0 ; python_version >= "3.9" and python_version < "4.0"
Some additional information: • Pants version: 
2.15.2
• Pex version: 
2.1.111
• OS: 
Ubuntu 22.04.3 LTS
• Virtualisation: 
Docker container on GKE
• Remote Cache/Exec with Buildbarn • 
interpreter_constraints = ["==3.9.*"]
• Code base consists both Python and Golang so sometimes Pants execution gets killed by OOM Sometimes, I managed to fix it with:
Copy code
rm -rf ~/.cache/{nce,pants} && rm -rf .pants.d && rm -rf ~/.pex && pkill pantsd
but not always. Then I try clearing pip cache and finally, reinstall my virtual env. Any tips on how I can progress with finding the root cause?
Closing the loop -> the error went away after bumping the memory (we are using virtual environments for development).

Thanks for the update!
