Hi guys!
I faced a ridiculous and unreasonable error in the reinforcement learning Lunar Lander assignment test cell that other students and I checked together, and we are sure there is no fault in the code (as my code is even similar to the hint of notebook!!!), but still, it is not solved so I can’t upload my assignment
The error is: “Wrong optimizer. Expected: <class ‘tensorflow.python.keras.optimizer_v2.adam.Adam’>, got: <class ‘tensorflow.python.keras.optimizer_v2.adam.Adam’>”
while I coded: "optimizer = Adam(learning_rate=ALPHA) "
I would be appreciative if anybody could help …
