my_model = deepforest.deepforest()
my_model.use_release()

Environment (please complete the following information):

• OS: Windows 10
• Python version and environment : Python 3.8 , Anaconda3 on Laptop

Hi @PravinM83 - it looks like you are using an old version of deepforest. We have recently switched from tensorflow to pytorch due to issues with external dependencies (see #195). Can you follow the new Installation (https://deepforest.readthedocs.io/en/latest/installation.html) and Getting Started (https://deepforest.readthedocs.io/en/latest/getting_started.html) guides and see if that takes care of things.

@PravinM83 - I'm going to go ahead and close this for now. Feel free to reopen if you're still having issues.
