It appears that you're experiencing problems exporting your TCNModel to ONNX. The error messages indicate that you must provide an input sample when calling 'to_onnx', yet the model's 'forward' method does not allow very many inputs.

Have you checked the 'forward' method of your '_TCNModule' to see what the intended signature is? You may need to change it or write a new function to prepare the input for ONNX export.

Additionally, it may be beneficial to provide more information about your model's architecture and the type of data it processes. That could help us better understand the problem you're experiencing.
