error: invalid path 'data/mp-n_elements<2.csv'

Interesting. Cloning works fine on Linux and macOS which means it's Windows specific. Seems '>' is not allowed in Windows file paths:

Use any character in the current code page for a name, including Unicode characters and characters in the extended character set (128–255), except for the following:

The following reserved characters:

< (less than)
> (greater than)
: (colon)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)

I'll just rename the file

git mv data/{mp-n_elements\<2,mp-elements}.csv

Can you let me know if cloning works now? Just occurred to me that since the offending path is still in git's history, it might still fail. If it fails, could you try git clone https://github.com/janosh/ml-matrics --depth 1 and let me know if that works? Either way, I'm not sure what's the right approach here. Purging the file from git history is possible but would break all existing forks that try to pull upstream. Since there are only two forks at the moment, I guess that's no big deal.

I was able to clone it just fine. Thanks for the fix! No need to mess with the history it seems.
