Please remove python-pydot-ng optdepend: discontinued in 2018, it's now deleted from AUR.

(Also its developer recommended everyone to use the main python-pydot instead.)

Here's a patch to update to 1.0.5:

I can help co-maintain this if you'd like.

import theano
ModuleNotFoundError: No module named 'theano'

Only worked after installing through PIP: $ sudo python -m pip install --upgrade theano

@xantares good suggestion about python2-parameterized. This package isn't necessary unless running check(), which takes over 4 hours to complete on my machine. Commented out python-parameterized and python2-parameterized from checkdepends().

xantares commented on 2019-03-31 12:30 (UTC)

please drop python2-parameterized

Thank you for the suggestion @xantares. Updated check-depends.

xantares commented on 2019-03-21 16:44 (UTC)

optdepends should moved to each package section else python-theano optionally requires python2-mpi4py:

checking dependencies...

:: python-theano optionally requires python2-mpi4py

Thanks for the helpful comments @xantares. I tried to move the numpy dependency like you said. I will keep working on it till I get things right.

Morganamilo commented on 2018-07-14 17:45 (UTC)

Looks like the maintainer might have taken my comment the wrong way. I said to move the global depends, the depends in the package functions should have stayed.

python-theano depends on python2-numpy, this is wrong

remove the global depends

move python-numpy and python2-numpy to makedepends

then add depends=(python-numpy) in package_python-theano

and depends=(python2-numpy) in package_python2-theano

Morganamilo commented on 2018-07-07 10:05 (UTC)

@cafehaine The issues seems to be because the pkgbuild defines the global depends then overrides them in the package. The global depends should either be removed or merged into the makedepends.

cafehaine commented on 2018-05-13 12:34 (UTC)

Cannot build because of missing dependencies (python2-numpy)

arvidsaur commented on 2017-11-29 15:57 (UTC)

Seems like pypi has dropped http support, but the pkgbuild works if you change the source to https.

Updated to python 3.6. check() commented out because it takes forever and uses lots of RAM. CPU checks pass on my computer, but take 4+ hours for everything to complete. GPU checks fail on my computer because my Geforce 9600 GT does not meet minimum CUDA requirements for this package.

Need to replace scripts-3.5 by scripts-3.6 with python 3.6.

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

jpate commented on 2015-10-06 15:55 (UTC)

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/

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: dnn_available.msg) 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.
