That’s a tricky error, as it just means the assertion failed which can have various reasons.
As of here, if you check the example output from the Readme and your output for the same data - you’ll notice your order in the output is different.
If I fix that, it runs without problem.
may i know how do u fix that ?
Basically, you switched axis1 and axis2 from the example. Meaning you have to switch the results for rows and columns in the lists for your final output.
It would be more obvious if you used the Numpy-methods to their full extend. You can both define a 3x3 shape in it and then utilize the axis-argument for “mean()” and so on…
You can fix the error by switching and then later look more into Numpy to optimize the code, if you’d like 
thank you so much! i appreciate the help
