I click on okay and the notebook gets truncated, I mean all of the cells after displaying the training set gets lost.
I am using Ubuntu 18.04 and Jupyter Notebook v5.7
Same problem with the DL1 notebooks.
Followed instructions verbatim at https://github.com/reshamas/fastai_deeplearn_part1/blob/master/tools/paperspace.md. Problem solved by deleting fastai directory and git clone from repo.
(fastai) paperspace@pskeqzz2p:~ rm -rf fastai (fastai) paperspace@pskeqzz2p:~ git clone https://github.com/fastai/fastai.git
I tried this, sadly the problem still exists.
