When I canceled download mnist data from website, it will always pop error on loading datasets

[Xiang Wang]

Hi all,

I canceled mnist dataset downloading process when running "lein run" command. But next time I run this command, it will always pop loading error - "Unexpected end of ZLIB input stream"

However, I did see where cortex saved the mnist dataset on my local machine. 

I think maybe just remove the truncked file it should work fine. 

So, would you guys tell me where the file is?

Thanks a lot.

~/.cortex on a unix system.  Not sure on a windows system.

Hi Shawn,

It sounds like the dataset on disk is not in good shape. Try deleting the folder ~/.cortex and run the tests again.

Here's the line of code that resolves the path, in case that helps:

Take care,
