Solve the problem of installing Theano on Ubuntu 19

Solution:

Directly in the directory where you downloaded the pythearn2 package, modify the setup.py file:
Changed from theano.compat.six.moves import input to from six.moves import input

Then you can:

python setup.py build
python setup.py install

ps: Install theano in Ubuntu environment

Recently, I need to install Theano. There are several ways to install Theano in Ubuntu. The simplest one is to pip install Theano directly, and then pip install any package that is missing. However, after I installed it, a problem occurred when I ran the code:

ImportError: cannot import name 'downsample'

After checking the information, I found that the latest version no longer has this feature. This is mainly an error caused by the Theano version update. The solution is

pip install theano==0.8.2

This can be used to change back to an older version.

Summarize

The above is the editor’s introduction to solving the problem of "No module named 'theano.compat.six'" when installing Theano in Ubuntu 19. I hope it will be helpful to everyone!
