I have trained a custom YOLOX model on google colab and want to convert it from .onnx to .ncnn.
I'm using the following as directions: https://github.com/Megvii-BaseDetection/YOLOX/blob/main/demo/ncnn/cpp/README.md#step4
Step 1 requires building ncnn with directions: https://github.com/Tencent/ncnn/wiki/how-to-build#build-for-macos
The directions give instructions for building on different devices.
My question: Which instructions should I use to build ncnn on Google Colab?
