#### Check volume difference metric ¶

Hi

I'd like to notice you that there is code you should check.

But, I found some error code.

I think it should change from "truth_vol = np.sum(**prediction**)" to "truth_vol=np.sum(**truth**)".

def volume_difference(truth, prediction, batchwise=False):

'''

Computes the total volume difference between the prediction and ground truth.

----------

prediction : np.array

Array containing the prediction.

truth : np.array

Array containing the ground truth.

batchwise : bool

Optional. Indicate whether the computation should be done batchwise, assuming that the first dimension of the

data is the batch. Default: False.

Returns

-------

float or tuple

'''

if(not batchwise):

pred_vol = np.sum(prediction)

truth_vol = np.sum(prediction)

return np.abs(pred_vol - truth_vol)

else:

It may be not problem (because the score is shown on leaderboard). But, The host should check this.
