Unittest function has code errors

Hello,

w1_unittest.test_translate(translate, trained_translator) has code errors that do not seem related to my code.

Is anybody experiencing the same problem?

When a unit test throws an error, it means it has detected an error in your code.

Your code is probably called from line “599”, where it calls g(). I suspect that’s a function pointer to one of your functions.

Exactly. That type of dimension mismatch error most likely means that your code is not general. E.g. it makes hard-coded assumptions about the dimensions of the input objects, but there are multiple test cases with different dimensions.

@TMosh , @paulinpaloalto , thanks for the help. I will check my code with those hints in mind.

@TMosh , @paulinpaloalto , may I bother one more time?

Never mind. I found and corrected my error.
