The parameter running_var in the batch normalization refers to the variance or the standard deviation?

I want to know the parameter running_var in the batch normalization refers to the variance or the standard deviation? Because I want to use the model pretrained in Matconvnet to init the pytorch model.

From the name I would guess variance.

This line of code seems to confirm your assumption.
