Hi @daniil-lyakhov,

I am encountering an issue with the test_depthwise_conv_default_quantizer_config test case in test_quantizer_config.py. The test is failing because the length of q_setup is 1 instead of the expected 2.

Upon further investigation, I found that the get_weight_nodes function for Torch FX min_max does not include the PTDepthwiseConv2dSubtype metatype in its list of recognized metatypes. As a result, the weight nodes variable in _get_quantizer_setup is empty, leading to the failure.

Could you please confirm if the PTDepthwiseConv2dSubtype metatype should be included in the list? If so, that should resolve the issue. Else, I'd appreciate some guidance.

Hi @rk119, Thank you for your investigation! You are right, I've forgot to include all metatypes for nodes with weights, good catch! Please replace current weighted metatypes list with this list.

Thanks a lot!
