Folks:

When I work on C3 Week3 Programming asisgnment Saimese Model Exercise 3 Train model, I got errors like this:

File “/usr/local/lib/python3.8/dist-packages/keras/src/engine/training.py”, line 1338, in train_function *

return step_function(self, iterator)

File “/tmp/ipykernel_14/512915329.py”, line 36, in norm *

return tf.math.l2_normalize(x, axis=1) # use tensorflow built in normalization

```
TypeError: Expected int32 passed to parameter 'y' of op 'Maximum', got 1e-12 of type 'float' instead. Error: Expected int32, but got 1e-12 of type 'float'.
```

I highly suspect it caused by Triplet loss function when I did:

def norm(x):

return tf.math.l2_normalize(x, axis=1) # use tensorflow built in normalization

```
sim = tf.linalg.matmul(norm(v2), norm(v1), transpose_b=True)
```

According to lab instructions. Anybody has any idea for that ?

Thanks.
