Hello, everyone
I called RoIAlignFunction from RoIAlignAvg
but there is an error
‘RoIAlignFunctionBackward’ object has no attribute ‘aligned_height’
How can I solve this problem???
Thank you in advance and have a nice day

def init(self, aligned_height, aligned_width, spatial_scale):
super(RoIAlignAvg, self).init()
self.align_function = RoIAlignFunction(aligned_height+1, aligned_width+1, spatial_scale)
def forward(self, features, rois):
    x = self.align_function.apply(features, rois)
    return avg_pool2d(x, kernel_size=2, stride=1)
