Bases: pytorch_lightning.callbacks.base.Callback. Quantization allows speeding up inference and decreasing memory requirements by performing computations and storing tensors at lower bitwidths (such as INT8 or FLOAT16) than floating point precision. We use native PyTorch API so for more information see PyTorch Quantization.
Model quantization is another performance optimization technique that allows speeding up inference and decreasing memory requirements by performing computations ...
Jul 22, 2021 · Tell PyTorch about the details of how to quantize including the quantization strategy, quantized dtype, which statistics to base the calibration on, by assigning a QConfig structure to our model as a member qconfig. PyTorch provides reasonable defaults, and PyTorch Lightning will set these for use when we let it know which backend we want. Fuse ...
