cannot import name 'np_utils' from 'keras.utils'

[nelsnelson]

I suppose some things must have changed since the course was released.

(venv) nelsnelson@neptuno:~/Documents/code/ml-class/videos/intro[master]$ python perceptron-single.py 
Traceback (most recent call last):
  File "/Users/nelsnelson/Documents/code/ml-class/videos/intro/perceptron-single.py", line 4, in <module>
    from keras.utils import np_utils
ImportError: cannot import name 'np_utils' from 'keras.utils' (/Users/nelsnelson/Documents/code/ml-class/venv/lib/python3.9/site-packages/keras/utils/__init__.py)

Hello Sir,
I think an import call can fix this problem.
Can you assign this issue to me?

[VoonaSriraj]

You should use:
from tensorflow.keras.utils import to_categorical
Then replace:
np_utils.to_categorical(y)
with:
to_categorical(y)

Is this issue still open or do this issue still needs solution?

[nelsnelson]

I will have to clone the latest revision of the code repository and check.

[abhipsa14]

Okay, let me know.

@abhipsa14 - Thanks for your attention for this issue. It appears that the error no longer occurs in the latest code revision.

I don't know what that output means, likely because I never completed the README past the original error.

However, I think that this issue can be closed.

Ok, thank you letting me know
