The torch.utils.tensorboard implementation uses a writer in core TensorBoard that supports GCS and S3 if TF is installed and S3 if not installed.I did not know this, this is very cool!
JIT can give you up to a 30% boost. With smaller batch-sizes (and feature map sizes) there is a smaller boost - 5-10%. Boost saturates with a certain batch-size / feature map size;int8 quantization can give you up to a 30% boost. Same caveats as with JIT;JIT+ int8, total speed ups up to 50%, also more equal speed ups for small batches and feature maps;ONNX however is generally faster than PyTorch out-of-the-box, but it is most pronounced for small feature-maps, e.g. you can get a 40% speed-up for small batch and zero speed-up for a large batch;ONNX + int8 does not seem to work in PyTorch now. We have not tried porting networks manually from ONNX to quantized ONNX;
