I am trying to run text generation example provided in ‘[GitHub - huggingface/optimum-habana: Easy and lightning fast training of 🤗 Transformers on Habana Gaudi processor (HPU)](https://github.com/huggingface/optimum-habana)’ in AWS DL1 instance. I receive Invalid Version error. I tried using the AMI as well but still receive the same. Not sure if I am missing something. Sharing the error:

Traceback (most recent call last):

I face the same issue while running other examples available in the repo.

Hi @ashwintcs! [This PR](https://github.com/huggingface/optimum-habana/pull/540) must have solved this issue. Have you tried again with the latest release or installing Optimum Habana from source?
