[theano-users] TypeError: 'KeysView' object does not support indexing

[Vinay Rajpoot]

i am working on project and occuring this traceback can anybody suggest me
what changes should i make in below section of code
for index in indices:
key = dataset_keys[index]
data_x = dataset[key]['features'][...].astype(_DTYPE)
L_distance_mat = cdist(data_x, data_x, 'euclidean')
L_dissim_mat = 1 - np.dot(data_x, data_x.T)

Traceback (most recent call last):
File "vsum_train.py", line 155, in <module>
train_dataset_path=args.dataset)
File "vsum_train.py", line 83, in train
key = dataset_keys[index]
TypeError: 'KeysView' object does not support indexing

It does not seem to have anything to do with Theano, but in Python3,
`dataset.keys()` would return a KeysView object, instead of a list like
in Python2.
That may be the reason.

Thanx, I have solved it by using python 2
