I try to test the batch norm with `fix_gamma=True`. The result on CPU is right, but that on GPU is wrong when `fix_gamma=True, axis = 1 and cudnn_off=False`. The `bn_beta` is the only wrong value. Here are the failure cases when `fix_gamma=True`. operator|shape|axis|cudnn_off|output_mean_var --|--|--|--|-- BatchNorm|(24, 2)|1|False|False BatchNorm|(24, 2)|1|False|True BatchNorm|(24, 3, 4)|1|False|False BatchNorm|(24, 3, 4)|1|False|True BatchNorm|(24, 4, 4, 4)|1|False|False BatchNorm|(24, 4, 4, 4)|1|False|True BatchNorm|(24, 8, 4, 4)|1|False|False BatchNorm|(24, 8, 4, 4)|1|False|True BatchNorm|(24, 5, 6, 4, 4)|1|False|False BatchNorm|(24, 5, 6, 4, 4)|1|False|True ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
