I get the same error when installing in Docker (base image ubuntu:24.04). I tried installing numpy before xtcocotools but the same ModuleNotFoundError error is raised.

Try upgrading your build tools:pip install --upgrade setuptools pip wheel This worked for me.

Try upgrading your build tools:pip install --upgrade setuptools pip wheel This worked for me.

This worked perfectly for me as well, thanks

I'm trying to install xtcocotools in Python 3.8 and getting the same issue; however, I couldn't solve the issue by upgrading build tools. The versions of my build tools are:

• setuptools 60.2.0 (needed for openxlab 0.1.2)
• pip 25.0.1
• wheel 0.45.1 and my platform is:
• Macbook M3 Pro
• macOS Sequoia 15.5
• Python 3.8.20. Apologies for the outdated versions; I am trying to clone an older repo. Any help is greatly appreciated!
