pip install fails in conda in windows environment

[nikky4D]

Computer: Win10, Package manager: Anaconda Python: 3.8

I did a pip install xtcocotools, and it keeps giving:

ERROR: Could not find a version that satisfies the requirement xtcocotools (from versions: none)
ERROR: No matching distribution found for xtcocotools

When I build from source by cloning the repo, and doing python setup.py install, I get:

Any help on this issue?

Thanks. Using the link, I removed the extra_compile_args=['-Wno-cpp', '-Wno-unused-function', '-std=c99'], then installed cython. That seems to work for the install.

Will the pip install be fixed soon?

Hello guys,

Same problem here. pip install gives me the same:

pip install xtcocotools
ERROR: Could not find a version that satisfies the requirement xtcocotools (from versions: none)
ERROR: No matching distribution found for xtcocotools

and when trying to install from sources on macOS 11.0.1 with python 3.6 I get

python setup.py install

Thank you for your help

Do you have cython installed for your system? I had similar issues in my install.

[lweingart]

Thank you @nikky4D ,

I installed cython and then was indeed able to install from source successfully. Thanks again
