I am using scikit learn metrics for this and used this code:
print('F1: {}'.format(f1_score(outGT, outPRED, average="samples")))
print('Precision: {}'.format(precision_score(outGT, outPRED, average="samples")))
print('Recall: {}'.format(recall_score(outGT, outPRED, average="samples")))

This is throwing this error:
ValueError: Classification metrics can't handle a mix of multilabel-indicator and continuous-multioutput targets

The output of
print('Ground Truth: {}'.format(outGT))
print('Predicted Truth: {}'.format(outPRED))

is as below:
Ground Truth: 
    0     0     0  ...      0     0     0
