Theano tensor import error

I have been trying to import

theano.tensor
in my code.
I have used
theano.tensor
before. All of my previous code importing
theano.tensor
works perfectly in my machine. Now I am trying to write another script importing the tensor from theano and I am getting the following exception.

Traceback (most recent call last):

I cannot find any plausible reason for this exception.

Answer

I guess i got your problem. See in the error log:

File "/anaconda3/lib/python3.5/pdb.py", line 75, in <module>
    import code

I believe there is another script called code.py in Theano which gets called from pdb.py when python interpreter executes your script which is also named as code.py. I am guessing python interpreter is mixing up these two scripts and executing the wrong one! You can change the filename and check whether the error disappear or not.
