Hi, thanks for developing epic2. I'm not to successfully run the example data generated from epic2-bw --example. Here are the error message:

Traceback (most recent call last):

Could you please solve this issue? Thank you in advance!

0.0.49 should be out soon. Mind checking if it works for you now? :)

Thanks for your reply. I've tried fixing this in 0.0.50. But I have no way to test the code on my machine as I have not set up a proper Python env on my new M1 mac.

Please tell me if it works or not :)
