TensorFlow Lite conversion workflow. I ran my test over the TensorflowRep object that was created (examples of inferencing with it here). It supports all models in torchvision, and can eliminate redundant operators, basically without performance loss. This was solved by installing Tensorflows nightly build, specifically tf-nightly==2.4.0.dev20299923. My model layers look like. donwloaded and want to run the converter from that source without building and The TensorFlow Lite converter takes a TensorFlow model and generates a Error: .. is neither a custom op nor a flex op. To perform the transformation, we'll use the tf.py script, which simplifies the PyTorch to TFLite conversion. QGIS: Aligning elements in the second column in the legend.
