Mismatch between CPU inference and GPU inference using metal-trained GRU

Regardless of the installation version combinations of tensorflow & metal (2.14, 2.15, 2.16), I find a metal/non-metal incompatibility for some layer types. For the GRU layer, for example, metal-trained weights (model.save_weights()/load_weights()) are not compatible with inference using the CPU. That is, train a model using metal, run inference using metal, then run inference again after uninstalling metal, and the results differ -- sometimes a night and day difference. This essentially eliminates the usefulness of tensorflow-metal for me. From my limited testing, models using other, simple combinations of layer types including Dense and LSTM do not show this problem. Just the GRU. And by "testing" I mean really simple models, like one GRU layer. Apple Framework Metal Team: You are doing very useful work, and I kindly ask, please address this bug :)
