Previous fix only iterated mel_converter._buffers (direct buffers). Submodules (e.g. Spectrogram.window) still held inference tensors. Switch to .modules() to cover all nested buffers, matching the vocoder parameter sanitization. Also add a zeros+copy_ safety net on target_mel output so conv can save it.
