Why do I get Resize is not callable?

I’m trying to create my own funcor for use in transformations, but it keeps failing with the error :
**TypeError** : 'Resize' object is not callable
This my example :

import torchvision.transforms.functional as F
class Resize(object):
    def __init__(self, size, interpolation):
        self.size = size
        self.interpolation = interpolation

    def __cal__(self, input):
        return F.resize(input, self.size, self.interpolation)

to_tensor_f = ToTensor()
import PIL.Image as Image
resize_f = Resize(3, Image.BILINEAR)
numpy_tensor = np.random.rand(2, 3)
result_tensor = to_tensor_f(numpy_tensor)
#resize this tensor!

Thank you all in advance

Got it. silly me mis typed __call__ as __cal__
fixed it and all is good
