I have been facing poor results while using scikit-learn accuracy whereas tensorflow's evaluation was good.

Here is the initial code:

# unbatch test_data and extract labels
y_labels = []

for image, label in test_data.unbatch():
    y_labels.append(label.numpy().argmax())

y_labels[:10]

It returns a serie of 0s.

Fix

label variable is a unique integer. So, argmax of an integer always returns 0.

To fix this, drop the .argmax() fonction.
