Hey! I was recently looking to speedup a python library that Im maintaining and bumped into mypyc. I immediately tried it out as it looked more promising than alternatives like Cython (we were already using mypy strict, so writing more type files wasnt ideal :) ). I keep hitting roadblocks with both type checking issues (mypyc/mypyc#883) and after a silly fix to the issue I just described, I keep getting AssertionErrors as well as a random KeyError. I have tried my best to look into it, but no luck. Could anybody point me in the right direction to fix the issue mentioned above (and then I will work my way down the rabit hole :P )
And thanks for building and maintaining this amazing tool, it is something that a lot of python programmers are in need of to get that little extra boost
Installing mypyc from the mypy repo seems to actually fix the empty assertion errors, I get tracebacks now!
This is one of them:

Hello, I will be joining college this year. I have learned the basics of Python in my high school and doing a bit of C++ right now. I am just getting started and am clue less, I was going through all the organizations and mypy interests me. Likewise, I am looking for guidance and how to proceed further, granted I want to contribute here.
Hi, I just joined this platform, I am a beginner, and I want someone to guide me through process, I have read getting started but I am not getting to the link of how to register for this company.
Also, I wanna know that is it for those who are intermediate or for those who are beginners too.

I know Python 3.10 isn't officially supported by mypyc but I wanted to ask if y'all are aware windows C compiler doesn't like lib-rt for some reason: https://github.com/ichard26/black-mypyc-wheels/runs/4060845577?check_suite_focus=true#step:5:3297
Anyone able to give me any insight to what maybe the issue. Bug in mypyc? or unsupported feature in my python?

Hey, I gave my first contribution to mypy. It hasn't been merged yet, are there any more changes required or the codes are merged at certain time intervals. If you want to check, my PR is #11453
How should I tackle this error??

Hi, I'm Max Shvets. I'm investigating this issue: mypyc/mypyc#899
I have trouble creating a test case for usages of AnyStr. I added the following to mypyc/test-data/run-misc.test:
[case testAnyStr]
from typing import AnyStr
def f(x: AnyStr, y: AnyStr) -> AnyStr:
return x + y
[file driver.py]
from native import f
print(f("3", "4"))
[out]
34However, when I try to run this test I get
run-misc.test:1160: error: Module "typing" has no attribute "AnyStr"Does anyone know what might be the issue here?
After some investigation, the issue was that the default
typing stub used for tests doesn't define AnyStr. In fact, none of the extended stubs in fixtures define it either. I want to fix this by defining AnyStr in mypyc/test-data/fixtures/typing-full.pyi and using [typing fixtures/typing-full.pyi] in the test. However, I noticed that adding [typing fixtures/typing-full.pyi] to the test results in mypyc not seeing the definitions in the test. I'll continue to investigate this and would appreciate any support
However, I noticed that adding [typing fixtures/typing-full.pyi] to the test results in mypyc not seeing the definitions in the test
The reason was that I added [typing ...] right after the [case ...], so the input field of DataDrivenTestCase was empty and nothing was written to native.py

Does mypyc have a “Compiled” switch like cython? (for runtime checking if code is compiled) https://cython.readthedocs.io/en/latest/src/tutorial/pure.html
How much python is required for gsoc?
Also, how much python machine learning is required for gsoc?
How can I contribute to gsoc like how can I find projects for contribution?
