## Details
<!-- Description of your issue -->
I saw the issue related to mine in #260 so I changed env to python 3.6 and torch 1.1 but I didn't help.
When I run onnx notebook I get an error [TypeError: export() got an unexpected keyword argument 'dynamic_axes']
Does anyone have guess what's wrong?

You can try newer version of PyTorch (like 1.3~1.5). The problem shall be resolved.<|||||>Hi thanks for the reply
I tried with pytorch 1.4 but I got another error on the below

do you have any idea about this one?
thanks!
<|||||>@amy-hyunji, this option (use_external_data_format) need PyTorch 1.5. This option is not needed for model < 2GB.

If you do not want to upgrade to PyTorch 1.5. You can install transformers from source, and modify the convert_graph_to_onnx.py  (by removing the parameter during calling onnx.export function).<|||||>@tianleiwu Thanks a lot :)
