Issue exporting to ONNX #81

Closed Mildemelwe closed 1 year ago

Mildemelwe commented 1 year ago

I'm getting an issue exporting my ckpt file to ONNX format. When I got this error before, I used oxygen-dioxide's ONNX export instead, and it worked, but now neither of them are working. The error is as follows:

Running ONNX simplifier...
Traceback (most recent call last):

Please use PyTorch 1.8

Thank you. I hadn't noticed, but for some reason my PyTorch version was changed in all my environments. It works now that I downgraded again.
