Problem with all the ML notebooks

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 Problem solved by deleting fastai directory and git clone from repo.

(fastai) paperspace@pskeqzz2p:~ rm -rf fastai (fastai) paperspace@pskeqzz2p:~ git clone

I tried this, sadly the problem still exists.
