I am using window 10 operating system

and when I try to run this project using Colab notebook

I get this error

ValueError: tf.function-decorated function tried to create variables on non-first call

in this step:

model.fit(dataset, epochs=EPOCHS)

Epoch 1/20 1/Unknown - 8s 8s/step --------------------------------------------------------------------------- ValueError Traceback (most recent call last) <ipython-input-42-d13425ded836> in <module>() 1 EPOCHS = 20 2 ----> 3 model.fit(dataset, epochs=EPOCHS)

ValueError: tf.function-decorated function tried to create variables on non-first call.

anyone could know what is the problem? it will mean the world to me :(

note': I haven't altered anything from the original source code
