hi, thanks for your community tutorial link.
MY PC is CPU i5-3470, and no GPU.
OS: windows 10 pro
env: miniconda
I wrote the code according to the instruction (GitHub - flashlin/deep_learning 2)
but it show the error message
tensors = pywrap_tfe.TFE_Py_Execute(ctx._handle, device_name, op_name,
tensorflow.python.framework.errors_impl.UnimplementedError:  Fused conv implementation does not support grouped convolutions for now.
         [[{{node StatefulPartitionedCall/wav2vec2/encoder/pos_conv_embed/conv/Conv1DWithWeightNorm}}]] [Op:__inference_restored_function_body_39909]
