Are you trying a direct download or 'wget' in devcloud?
It would be great if you can try it once more (preferably on a different browser) and send a screen shot of the same.
I have been using direct download on Google Chrome as wasn't sure on the wget url. However, I have since tried direct download on Firefox and also wget on the files in question.
In each case I appear to download the zip file correctly but when unpacking there is no .pdf or .ipynb. This gives the same error for Tensorflow 3/4/5/7/8.
I also have an issue when downloading the Deep Learning week 12 where it downloads fine again but am unable to unpack at all.
I have attached a video which shows that Tensorflow 1 works fine and it fails for Tensorflow 3 & also for Deep Learning 12.
Good to hear that.
The issue may be related to your decompression software.
