assertion error assert optimizer in ["sgd", "adagrad", "adam", "momentum"]

File "tensorFlow/Deep-Learning-TensorFlow/yadlt/core/trainers.py", line 27, in init assert optimizer in ["sgd", "adagrad", "adam", "momentum"] AssertionError

Is that due to a program bug? Anyone knows how to fix it?

Thanks.

The error comes out when I tried to run the example code of Stacked Deep Autoencoder

same for me when I run it
