Thanks soupault!

I didn't notice the permission issue in the -0 release. I fixed it in the -1 release.

If you have the permission problem you can fix it in one of the two ways:

1) Preferred: Remove python-theano &/or python-theano2 Then re-install from most recent PKGBUILD

2) change the permissions of /usr/lib/python3.5/site-packages/Theano-0.8.0-py3.5.egg-info to 755 and /usr/lib/python3.5/site-packages/Theano-0.8.0-py3.5.egg-info/* to 644

Hope this helps. Please let me know if the above doesn't work for you.

Hi! The latest update ships permission errors. See for the details. Same for `python2-theano`.

For example, permissions for `scikit-image`:
-rw-r--r-- 1 root root 1,4K mar 9 20:40 PKG-INFO
and for the latest `theano`:
-rw-r----- 1 root root 11K mar 24 22:52 PKG-INFO

Thanks jpate, updated for Python 3.5

After the update of python to 3.5, the line that copies build scripts (line 41) needs to be updated to:

cp -f build/scripts-3.5/* bin/

Thanks for the feedback M01. The package might implicitly have an optional requirement for pygpu, and perhaps cudnn if cuda is present.

I have commented out the check() function in the PKGBUILD, as the tests are lengthy and only seem to work on x64 systems without optional dependencies installed.

I'll happily accept any patches and/or suggestions for improvement. I would love to get check() to always work. Unfortunately, I simply do not have the time right now.

Does this package implicitly require cudnn, if a CUDA-capable graphics card is present? I get 193 test failures (after 8h of testing..), most of which look like this:

Exception: ('The following error happened while compiling the node', GpuDnnConvD
esc{border_mode='full', subsample=(1, 2), conv_mode='cross'}(MakeVector.0, MakeV
ector.0), '\n', "We can't determine the cudnn version as it is not available", '
Theano can not compile with cuDNN. We got this error:\n/tmp/try_flags_a6sjL4.c:5
:19: fatal error: cudnn.h: No such file or directory\ncompilation terminated.\n'

The last error I get is this:
