Answer 1

Your problem is that you are trying to load from disk with path of your computer!

Collab gives you a completely different computer in the cloud to work with so it wont be able to open the files in your computer:

You have to upload files to collab:

Use this function to upload files. It will SAVE them as well.

def upload_files():
  from google.colab import files
  uploaded = files.upload()
  for k, v in uploaded.items():
    open(k, 'wb').write(v)
  return list(uploaded.keys())
