AttributeError: module 'autograd.numpy' has no attribute 'numpy_extra'

[muszyna25]

Hi, I am currently working on a code (Python 2.7) that was written about 5 years ago. The code uses Autograd and it looks like that module 'autograd.numpy' has no attribute 'numpy_extra'. This is an error that I am getting: AttributeError: module 'autograd.numpy' has no attribute 'numpy_extra'.

Here is the snippet of the code where this error comes from:
if type(self.DIVERSITY) is autograd.numpy.numpy_extra.ArrayNode: self.DIVERSITY = self.DIVERSITY.value[0,0]

Would you be able to advise how this autograd.numpy.numpy_extra.ArrayNode was replaced/changed in the latest release of the Autograd, please?

Thank you!
