Cannot debug Python code in PyCharm

[vmax]

Description

Currently, it's impossible to debug py_binary/py_test in PyCharm; this is a sample exception message:

/usr/bin/setsid --wait /usr/bin/python3.8 /snap/pycharm-community/205/plugins/python-ce/helpers/pydev/pydevd.py --multiproc --qt-support=auto --client 127.0.0.1 --port 46541 --file /home/vmax/.cache/bazel/_bazel_vmax/379e6d40d9b6adee7e2caab387d392a8/execroot/__main__/bazel-out/k8-fastbuild/bin/test
pydev debugger: process 80673 is connecting

Connected to pydev debugger (build 201.8743.11)
Fatal Python error: init_sys_streams: can't initialize sys standard streams
Python runtime state: core initialized
Traceback (most recent call last):
  File "/usr/lib/python3.8/io.py", line 78, in <module>
    class BufferedIOBase(_io._BufferedIOBase, IOBase):
  File "/usr/lib/python3.8/abc.py", line 85, in __new__
    cls = super().__new__(mcls, name, bases, namespace, **kwargs)
KeyboardInterrupt

Process finished with exit code 1

What's curious is that with every debug rerun it's having a different stack trace (KeyboardInterrupt is always the last element)

Reproducible example

BUILD:

py_binary(
    name = "test",
    srcs = ["test.py"],
)

test.py:

import sys
print(sys.path)

Configuration

OS: Ubuntu 20.04
PyCharm version: pycharm-community (2020.1/stable); installed via Snap
Python: 3.8.2
Plugin version: reproduced both on latest released version (2020.07.13.0.2) and one built from latest master (commit sha 43c4949a35bcde233c2f1b9bd2c6ecfdfa93acb6)

An older PyCharm bug indicated that switching on Attaching to subprocess automatically while debugging is an issue.

https://intellij-support.jetbrains.com/hc/en-us/community/posts/360003290559-KeyboardInterrupt-when-debugging-a-PyTorch-project

I tried turning this off and then the debugger says that it cannot debug because the main process has a subprocess.

I'm experiencing this the issue as well and would love to hear if there's a possible workaround. I cross posted on the Bazel slack as well.

I have to manually update pydevd. Explanation here: #402

See this comment for a fix with latest bazel version and latest intellij: #402 (comment)

Has there been any progress on this issue? I'm in 2022 on PyCharm 2022.2 and Bazel plugin 2022.08.09.0.1-api-version-222, but debugging doesn't work either

UPD: I had a closer look at the output, turns out, I updated PyCharm after I got the first error (as in the topic description), and when I got an error after the update, I assumed it was the same. But it isn't. Here's what I am getting now:

I'm on MacOS 12.4, java 17.0.1 2021-10-19 LTS,
PyCharm 2022.2 ce
Build #PC-222.3345.131, built on July 27, 2022

Is there anything I can do to fix this?

Hey @therearesomewhocallmetim, debugging works for me, despite the error you mentioned (I get it, too)

Closing, as this is likely to be fixed, please fill free to reopen if it still doesn't work for you
