"Folder does not exist or is not reachable"

Hi, I’m on digits:latest trying to create a new object detection dataset. However, it keeps telling me that the “folder does not exist or is not reachable”, even when it’s present.

I’ve attached some screenshots below:

My command to start digits is: docker run -v nvidia/digits/data/ -p 5000:5000 nvidia/digits:latest
My driver version is 418.88 and cuda version is 10.1
My ubuntu version is https://prnt.sc/pjnsb9

Here are the specs of my computer:
i7-7700HQ, Geforce GTX 1050 mobile

Thanks!
