Lesson 1 - directory data/dogscats/tmp is not writable

The code below used to work, but now at least pre-computing does not. I don’t understand the error.

Good steps. Here’s how I fixed it:

Previously I had run these lines:

os.makedirs(’/cache/tmp’, exist_ok=True)
!ln -s /cache/tmp {PATH}

I figured the directory was created and linked up, however /cache/tmp had dissappeared (maybe the /cache directory is emptied regularly?). Running the following line again fixed things:

os.makedirs(’/cache/tmp’, exist_ok=True)

On crestle you have to run those lines every time you start a new instance, since /cache is recreated at that time.
