the error occurs because TensorFlow 2.10.0 isn’t available as a standard wheel for macOS arm64, so pip can’t find a compatible version for your Python 3.8.13 environment. If you’re on Apple Silicon, you should replace tensorflow==2.10.0 with tensorflow-macos==2.10.0 and add tensorflow-metal for GPU support, while also relaxing numpy, protobuf, and grpcio pins to match TF 2.10’s dependency requirements. If you’re on Intel macOS, you can keep tensorflow==2.10.0 but still need to adjust those dependency pins. Alternatively, the cleanest fix is to upgrade to Python 3.9+ and TensorFlow 2.13 or later, which installs smoothly on macOS and is fully supported by LibRecommender 1.5.1
