Installing package on Windows fails on too long filenames

Installing onnx fails on my Windows 10 machine due to filepaths being too long (“De bestandsnaam of -extensie is te lang” is dutch for “The filename or -extension is too long”):

ERROR: Could not install packages due to an EnvironmentError: [WinError 206] De bestandsnaam of -extensie is te lang: 'c:\\users\\korij_000\\appdata\\local\\pypoetry\\cache\\virtualenvs\\zb-hps-algo-bkp0o5gs-py3.6\\Lib\\site-packages\\onnx\\backend\\test\\data\\node\\test_negative_log_likelihood_loss_input_shape_is_NCd1d2d3_none_no_weight_negative_ignore_index_expanded\\test_data_set_0'

I am able to work around this issue by installing to a folder higher up in my filesystem, but this filename looks a bit excessive.

If I may make a suggestion: don’t include your tests and especially your test data in your wheels. It’s not needed at runtime and makes the package much bigger.

Thanks for the advice.

I read that you ended up not removing the test data because people are apparently using it? Just keep in mind that more and more people will start using the test data in the package and it will become harder and harder to remove it the longer you wait.

Just like there are alternative methods to deal with long paths as you explained, there are alternative ways to distribute test data too 😃 for example, they could use git clone and use command line options to shallowly retrieve just your test data folders.
