TypeError: Singleton array array(67, dtype=int64) cannot be considered a valid collection.

Hi,When I was running UCF101_3DCNN.py, I got the following error:
......
File "...... .\lib\site-packages\sklearn\metrics\classification.py", line 71, in _check_targets
check_consistent_length(y_true, y_pred)
File "...... .\lib\site-packages\sklearn\utils\validation.py", line 200, in _check_consistent_length
lengths=[_num_samples(X) for X in arrays if X is not None]
File "...... .\lib\site-packages\sklearn\utils\validation.py", line 200, in
lengths=[_num_samples(X) for X in arrays if X is not None]
File "...... .\lib\site-packages\sklearn\utils\validation.py", line 119, in _num_samples
" a valid collection." % x)
TypeError: Singleton array array(67, dtype=int64) cannot be considered a valid collection.

The batch_size is resized as 5, 10, 15, 45, 60, 100, ...... respectively, but this issue exists yet.

Hi,did you solve the issue? I meet the same ploblem.Thanks.

Hi,did you solve the issue? I meet the same ploblem.Thanks.

May I ask if you have solved it now? I also met the same problem

UCF101_3DCNN.py line 59 step_score = accuracy_score([y.cpu().data.squeeze().numpy()], [y_pred.cpu().data.squeeze().numpy()]) the parameters of accuracy_score() need to be array-like etc., so the correction is likes to the above line. please let me receive your reply if you solve the problem.

check if you use CPU ，the BatchSize =1 will cause this problem

check if you use CPU ，the BatchSize =1 will cause this problem

So using GPU will solve this problem?

not necessary, just add [ ] because this is needed in sklearn.
