tensorflowjs_converter fails on python3.13

[NormanTUD]

It fails to install and doesn't work with tf_nightly if installation is forced. As this is the latest version available on, for example, Debian, and tensorflowjs_converter is required to use models ie created in the browser, it would be highly appreciated to finally start supporting the latest versions.

Hi @NormanTUD ,

I am unable to reproduce the reported issue with Python 3.13.5 and I can install tfjs_converter. I am trying to replicate the issue in the following gist. Could you please verify if my approach is correct? If possible, could you share the specific code/commands that I can use to replicate the problem on Python 3.13? Thank you.

Hi,

I have Python 3.13.3 and I do this:

python3 -mvenv test_env
source test_env/bin/activate
pip install tensorflowjs

and I get this:

I am not sure what else you need to replicate this. Would love to have this work, though.
