Error while running

I'm getting following error.

I think that error comes from an outdated skimage version, try pip install --upgrade scikit-image

[quintendewilde]

Upgraded it and got new errors...
Very stranged because I followed the installation just 3days ago so it's also strange that it's outdated... Though I am new at this, probably oversaw something.

These errors don't look to me like they come from my scripts? Apparently they request you to execute /data/download-lfw-subset.sh in order to download the LFW dataset.
Are you sure this is the project that you used three days ago? It looks like you are trying to do something with OpenFace.

[quintendewilde]

Yeah I found a stack page with it have something to do with my command line tools probably.

I would like to ask you how to solve this problem?

ValueError: Invalid mode specified. Please use constant, edge, wrap, reflect or symmetric.
What does this mean? Do you know what caused it?

[aleju]

Try upgrading your scipy and scikit-image, I think that error pops up with outdated versions. I.e. do something like: sudo pip install --upgrade scipy scikit-image

I had the same error as described above. @aleju, please checkout the script dataset/generate_dataset.py in line 130, I changed the value of mode to 'constant' and It runs until stops at another error in line 40, currently the value is 'nearest', as the error says that value is invalid.

[aleju]

Fixed the one in line 130, thanks for the info.
What other error are you getting? generate_dataset.py seems to run fine for me. Probably some problem with a newer version of a library. I currently can't update here, so I can't check that.

Hm not sure what your problem here is. That stacktrace isn't very useful and stops at a point where it shouldn't throw an IOError. I just tried executing the script and get way past image 27. The best I could find online was that it seems to be an error that can sometimes pop up in windows when reading and writing to the same file, but that shouldn't be the case here.
