Do stuff with image crashes

While running the notebook: lets-chat_with_a_friend.ipynb

Perhaps there are no faces detected? Does this only happen in the notebook file or also in the regular python file?

[piekvossen]

This is image that is loaded according to the code

[tae898]

Alright I see the problems now.

The directory paths have been changed. The modules can't find each other now.

I suggest following:

1. Go back to the last commit.
2. Module names should be more explicit (i.e., src is not a good name for a module. We are coding in python, not c++).
3. It's always better to make PRs, especially when there are breaking changes.

Hm, but it's not an import error, right? Looks to me like the python path is set correctly.

[piekvossen]

Fixed and code cleanup. I added arguments for setting the paths for the embeddings throughout the code. All logs, data, embeddings are outside the src folder and a chatbots packages was added.
