Hello, I have the exact same issue when training any RNN (I tried both LSTMs and GRUs) model with my MBP16 with M1 Max 32C. I get the same exception/warning, and the performance with the GPU is horrible. Disabling the CPU results in no warning, and better performance. I don't have the same issue with CNNs. All of this is with the latest tensorflow-macos (2.10) and tensorflow-metal 0.6.

Same issue here, unfortunately. Are there any news?
