No module named 'torch' when pip install -e .

[rabum]

When I tried to install the project with line pip install -e . there seems to be a problem:
DEPRECATION: Legacy editable install of detectron2==0.6 from file:///home/yunzheng/devit (setup.py develop) is deprecated. pip 25.3 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information. Discussion can be found at pypa/pip#11457

Have you solved it? I've run into the same problem too.

Did anyone find the solution? I have the same issue.

Same problem,

@huytuong010101 nào fix được chỉ anh với nha :)))

@KudoKhang qua install repo ni anh giai: #88

Anh chạy được rồi, không biết có sai sót gì không mà thời gian inference 1 phút lận. Em cũng đang làm ZaloAI challenge hở

[huytuong010101]

yup, lâu z hả z thôi e khỏi thử 😄

[zhuomo-1]

Downgrading setuptools could solve this problem.
You can run pip install "setuptools<60" before running pip install -e .

[hongtao11]

use the "pip install -e . --no-build-isolation" have successful install at linux
