08.09.2019 · I was also using np.uint8 in one array which I later used to create PyTorch tensor. I changed that to np.bool_ now. The problem is that I still have thousands of the same messages and as I am not explicitly using uint8 anywhere now, I wonder where it might come from? Does PyTorch still convert some numpy data to torch.uint8?
torchvision.transforms — Torchvision 0.11.0 documentation
https://pytorch.org/vision/stable/transforms.html
torchvision.transforms¶. Transforms are common image transformations. They can be chained together using Compose.Most transform classes have a function equivalent: functional transforms give fine-grained control over the transformations. This is useful if you have to build a more complex transformation pipeline (e.g. in the case of segmentation tasks).
torch.Tensor.to — PyTorch 1.10.1 documentation
https://pytorch.org/docs/stable/generated/torch.Tensor.to.html
Returns a Tensor with the specified device and (optional) dtype.If dtype is None it is inferred to be self.dtype.When non_blocking, tries to convert asynchronously with respect to the host if possible, e.g., converting a CPU Tensor with pinned memory to a CUDA Tensor.When copy is set, a new Tensor is created even when the Tensor already matches the desired conversion.

24.06.2020 · I see. To summary what I understood, the quantization step is done as follow. Load pretrained fp32 model; run prepare() to prepare converting pretrained fp32 model to int8 model; run fp32model.forward() to calibrate fp32 model by operating the fp32 model for a sufficient number of times. However, this calibration phase is a kind of `blackbox’ process so I cannot …

PyTorch Uint8 might be equivalent to Numpy Bool, but not ...
christopher5106.github.io › torch › 2019/06/23
Jun 23, 2019 · PyTorch Uint8 might be equivalent to Numpy Bool, but not always Numpy Uint8. A subtlety for array indexing: Until now, everything looks fine. And if we use integers, Numpy considers it as indexes: The integer values 0 and 1 in b array are considered as taking a [0] and a [1] (which are vectors of dimension (5,)).

Quantization — PyTorch 1.10.1 documentation
pytorch.org › docs › stable
PyTorch supports multiple approaches to quantizing a deep learning model. In most cases the model is trained in FP32 and then the model is converted to INT8. In addition, PyTorch also supports quantization aware training, which models quantization errors in both the forward and backward passes using fake-quantization modules.
