can't import fastinference.onnx

[hududed]

Hi @muellerzr

I am running fastinference==0.0.32, fastai==2.1.9 and fastcore==1.3.12.

When I try to import from fastinference.onnx import * to use fastONNX class I get this error:

When I use fastai==2.1.5 and fastcore==1.3.2 this problem doesn't exist, but not using the updated fastai would cause other problems when running fastai interpretations eginterp.plot_top_losses.

Thanks for pointing this out! Looks like there was one more fastcore issue I needed to solve. Can you try again with installing fastinference like so?

pip install git+https://github.com/muellerzr/fastinference

Hi @muellerzr that seems to have worked! the import and interp.plot_top_losses works as usual.

[muellerzr]

Great! I'll update the pip version later today when I can

Updated pip, closing
