Theano: ImportError: cannot import name inplace_increment

[9thDimension]

Just got the latest Theano 0.9.0b1 using sudo pip install git+git://github.com/Theano/Theano.git

>>> import theano
Couldn't import dot_parser, loading of dot files will not be possible.

This is on Centos 7.

I'm pretty sure this is related to having an old Theano cache.

Can you delete it? "theano-cache purge". If that don't work, by default it is under ~/.theano

@nouiz hi, I want to know where I should input the command "theano-cache purge".
My problem is
NotImplementedError: Could not import inplace_increment, so some
advanced indexing features are disabled. They will be available if you
update NumPy to version 1.8 or later, or to the latest development version.
You may need to clear the cache (theano-cache clear) afterwards.

but my numpy is 1.11.3, why I still get the problem?

[nouiz]

delete the cache manually if theano-cache don't work:

rm -rf ~/.theano

and update Theano:

sudo pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git
