[GitHub] [incubator-mxnet] OliverColeman opened a new issue #19752: Allow Symbol arguments for BilinearResize2D width, height, scale_*

[GitBox <gi...@apache.org>]

OliverColeman opened a new issue #19752:
URL: https://github.com/apache/incubator-mxnet/issues/19752


   ## Description
   `ndarray.contrib.BilinearResize2D` expects the  `width`, `height`,  `scale_width` and `scale_height` parameters to be scalar ints or floats. The request here is to allow passing a Symbol for these parameters. The Symbol values could come from, for example, the `nd.shape_array()` function. This would allow, for example, specifying the output size of the Bilinear operation based on the dynamic shape of previous input or stages in both imperative and symbolic mode in a hybridized model:
   
   ```
   def hybrid_forward(self, F, x):
           original_size = x.shape_array()[2:]
           ...
           x = F.contrib.BilinearResize2D(x, height=original_size[0], width=original_size[1])
           return x
   ```
