I am using Theano. The OS is Ubuntu. The Theano is UPTODATE. I am wondering why I am getting by from theano.tensor.signal.downsample import max_pool_2d command.

ImportError: No module named downsample.

The downsample module has been moved to pool, so try declaring it as:

from theano.tensor.signal.pool import pool_2d

After changing delete your theano cache with the command:

theano-cache purge

Try doing the following ( code here ) to find the location of the cache, that's what you'll want to delete to make sure the imports are updated. – Houle 15/9, 2016 at 0:4

Thank you. It gives me an address. What is the next? – Dais 15/9, 2016 at 0:8

You'll want to delete the contents, as it's the cache which contains outdated imports. – Houle 15/9, 2016 at 0:9

Thank you. Now. ImportError: No module named Theano.tensor.signal.pool – Dais 15/9, 2016 at 0:12

It should be lowercase "theano", not "Theano". As a test try doing the following: gist.github.com/anonymous/8a65c27f4e65e0ed5ad8ce124dab36af – Houle 15/9, 2016 at 0:15

^ did you try lowercase "theano"? If the error persists then you must not have a completely current version -- sudo pip install --upgrade --no-deps theano – Houle 15/9, 2016 at 0:25

update theano and lasagne

pip install --upgrade https://github.com/Theano/Theano/archive/master.zip
pip install --upgrade https://github.com/Lasagne/Lasagne/archive/master.zip

Lasagne vs Theano possible version mismatch (Windows)

Try to update the Theano using this link.

pip install --upgrade https://github.com/Lasagne/Lasagne/archive/master.zip

Same issue [theano v.0.9.0dev1.dev-2...]; changed

from theano.tensor.signal import downsample
pooled_out = downsample.max_pool_2d( ... )

to

from theano.tensor.signal import pool
pooled_out = pool.pool_2d( ... )

in /lib/python2.7/site-packages/lasagne/layers/pool.py
