This is what you should expect: If you want to test the model with its TFLite weights, you first need to install the corresponding interpreter on your machine. Indefinite article before noun starting with "the", Toggle some bits and get an actual square. Launch a Jupyter Notebook from the directory Asking for help, clarification, or responding to other answers. In our experience, a discrepancy at this stage, in pretty much every case, doesnt come from a difference inside the models but from a discrepancy in the way the inputs are prepared, in the optimization parameters (one of the most often over-looked ones being the batch size) or in the post-processing and evaluation metrics. The converted Tensorflow graph having the output being detached from the graph. Webconvert pytorch model to tensorflow lite. After selecting the Infery inference engine.
