I'm learning deep learning by taking a lecture that uses fastai. I'm running fastai library on AWS p2.xlarge. When I ran some function on fastai library I get this error.:

Traceback (most recent call last)

221     except OSError:
222         # Cannot rely on checking for EEXIST, since the operating system

PermissionError: [Errno 13] Permission denied: 'data/dogscats/tmp'

I think the AWS console has no permission to make the directory. I did sudo mkdir tmp data/dogscats/ but I get another error that I couldn't understand.

I think I have to give AWS some permission but I have no clue how to do that.

I hope you guys can give me some clear idea on how to solve this kind of problem.

  • "_I did sudo mkdir tmp data/dogscats/_": I'm not sure if that's a typo, because the error is referring to the directory *data/dogscats/tmp*. Maybe the error that you got with that command is that you entered the command incorrectly? – Gino Mempin May 12 '19 at 01:32

Fastai creates saves data like current loss etc. in a folder it creates by default the folder is created in the working directory but you can pass the argument path that is the path where you have the privileges to create a folder.
