C2W3 Problem downloading pretrained weights

I got an error:
'str' object has no attribute 'decode'
When running locally:

Do you know how I can fix it?

pre_trained_model.load_weights takes a string the points to the path where the weights file is saved. Keep in mind that once a linux machine is restarted, whatever is in /tmp can be cleared.
If the weights file is stored in that path, please click my name and message your notebook as an attachment.
