setuptools version

75.2.0

Python version

3.11.8

OS

Ubuntu 20.04.6 LTS

Additional environment information

Server: Intel(R) Xeon(R) CPU E5-2695 v4 @ 2.10GHz Python: 3.11.8 (conda) pip: 24.2 (latest) pandas-ta: 0.4.19b0 (latest) attributedict: 0.3.0

Description

Problem: I can not import pandas-pta lib because of error below. I created issue on official page https://github.com/twopirllc/pandas-ta/issues/831, but author said I need to ask here. Error is because of importing attributedict lib. Without it everything works.

Expected behavior

print('ok')

How to Reproduce

# Version: 0.3.0
from attributedict.collections import AttributeDict

# Version: 0.4.19b0
import pandas_ta as pta

if __name__ == "__main__":
    print('ok')

Output

Hi @fridary, the code you highlighted iterates over sys.path, so it is indeed surprising that it is finding a None object.

Could you please double check that all the entries in sys.path are not None in your environment, before and after importing the attributedict?

fridary commented 1 month ago

@abravalheri is it what you are asking for?

Before importing attributedict:
/home/sirjay/python/ethereum
/home/sirjay/miniconda3/envs/eth/lib/python311.zip
/home/sirjay/miniconda3/envs/eth/lib/python3.11
/home/sirjay/miniconda3/envs/eth/lib/python3.11/lib-dynload
/home/sirjay/.local/lib/python3.11/site-packages
/home/sirjay/miniconda3/envs/eth/lib/python3.11/site-packages

After importing attributedict:
/home/sirjay/python/ethereum
/home/sirjay/miniconda3/envs/eth/lib/python311.zip
/home/sirjay/miniconda3/envs/eth/lib/python3.11
/home/sirjay/miniconda3/envs/eth/lib/python3.11/lib-dynload
/home/sirjay/.local/lib/python3.11/site-packages
/home/sirjay/miniconda3/envs/eth/lib/python3.11/site-packages
None found in sys.path!

Yes, thank you very much.

So, for some reason,attributedict (or any of its dependencies) is adding None to sys.path, which seems to be the root cause of the problem (if you remove the None entry, the code will probably work).

That does not seem quite right, does it? According to the docs, sys.path is supposed to contain a list of strings: https://docs.python.org/3/library/sys.html#sys.path , so adding None to sys.path can be considered a detective behaviour.

You should probably try contacting attributedict about that (or narrow down to one of its dependencies).
