Importerror: No Module Named Downsample

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 mod

Solution 1:

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)

Solution 2:

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

from theano.tensor.signal.poolimport pool_2d

After changing delete your theano cache with the command:

theano-cache purge

Solution 3:

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

from theano.tensor.signal importdownsamplepooled_out= downsample.max_pool_2d( ... )

to

from theano.tensor.signal importpoolpooled_out= pool.pool_2d( ... )

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

Solution 4:

Try to update the Theano using this link.

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