@Erye The name of the output folder should be the last argument of the command, it is missing here. It should work with:

optimum-cli export onnx --model bert-base-uncased onnx_model

What is the version of Optimum you are using? With the latest release, you should get an error message such as this one:

optimum-cli export onnx: error: the following arguments are required: output

I’m currently stuck with the same issue.
I’m running the following command
optimum-cli export onnx -m my-Model-name.pth out

File “c:\users\myUser\appdata\local\programs\python\python38\lib\site-packages\optimum\exporters\tasks.py”, line 1261, in get_model_files
return all_files, request_exception
UnboundLocalError: local variable ‘all_files’ referenced before assignment

Used version:
optimum==1.14.0

Do you know what I’m missing?

Hi @Anyeahh! Could you try again replacing my-Model-name.pth by the name of the folder it is located in please?
