AttributeError: 'NoneType' object has no attribute 'inline'

[sulimani]

I'm trying to run your code and I'm getting the following error: 'NoneType' object has no attribute 'inline'

I tried to run the code using PyCharm on virtual Ubuntu 18.4 and I installed all the packages required. It didn't work. So, I installed Anaconda 2 and I tried to run it on Spyder, but I got the same error as well.
Can you please advise me on how to solve this issue.

Hi @sulimani, I'm not really supporting this code anymore, but you can find similar code here and here.

As for your error, it looks like there's a problem with your brian / weave installation; I recommend trying to fix the problems with those packages. However, the version of brian (and other packages, I'm sure) used for this project are now out of date. So, I don't really expect it to work.

Hi, It's tehreem.I have an issue while evaluating this code.
The error is like is:
sum_accurracy = [0] * num_tests
TypeError: can't multiply sequence by non-int of type 'float'.
What should i do?
Waiting for your kind reply.
Thanks
