Conversion of mask_depthwise_convolution to Torchscript does not work

[atishay14]

Hi All,

When I try converting the mask_depthwise_convolution module to Torchscript using the code at https://github.com/jiwoong-choi/SiamMask I get the following error:

Expected a default value of type Tensor on parameter "pos"

Please help me resolve this.
