🐛 Bug

Interpolate with bilinear results in

RuntimeError: Unsupported prim::Constant kind: `s`. Send a bug report.

To Reproduce

Steps to reproduce the behavior:

@torch.jit.script
def image_pool(crop, new_h, new_w):
    resized = interpolate(crop, (int(new_h), int(new_w)), mode='bilinear')

or

@torch.jit.script
def image_pool(crop, new_h, new_w):
    resized = interpolate(crop, (int(new_h), int(new_w)))

Expected behavior

Export bilinear interpolation, also print the string in the error message by changing to

                    raise RuntimeError("Unsupported prim::Constant kind: `{}` in `{}`. Send a bug report.".format(n.kindOf("value"), n))
