Hi all,
This is not strictly a Theano error, but it arises whenever you run the
PyCharm debugger on any code that imports theano.
For some reason, when running in debug mode, with any code that imports
theano, I get the additional error message:
Exception TypeError: TypeError("'NoneType' object is not callable",) in <
function _remove at 0x10e0f47d0> ignored
I am also unable to "break on exception", which is a useful feature when
debugging code.
I guess Theano does something sneaky under the hood which unintentionally
messes with PyCharm's debugger.
Example: When I run the following code in PyCharm's debugger:
import theano
def demo_theano_pycharm_error():
raise Exception('My error')
demo_theano_pycharm_error()
I get the output:
