Description
I’ve just tried to quantize a model with ConvTranspose1d using torch 1.8 and fbgemm backend, but got this error message: AssertionError: Per channel weight observer is not supported yet for ConvTranspose{nx}d.
Pitch
Quantization of a model with ConvTranspose works fine with default qconfig using the most reliable per channel quantization.
Alternatives
There's an option to use per tensor configuration instead, though it's typically less accurate.
