torch.cuda — PyTorch 1.11.0 documentation torch.cuda This package adds support for CUDA tensor types, that implement the same function as CPU tensors, but they utilize GPUs for computation. It is lazily initialized, so you can always import it, and use is_available () to determine if your system supports CUDA.

Sets the random number generator state of all devices. Parameters. new_states (Iterable of torch.ByteTensor) – The desired state for each device. torch.cuda.

to set cuda as your device if possible. There are various code examples on PyTorch Tutorials and in the documentation linked above that ...

CUDA semantics — PyTorch 1.11.0 documentation CUDA semantics torch.cuda is used to set up and run CUDA operations. It keeps track of the currently selected GPU, and all CUDA tensors you allocate will by default be created on that device. The selected device can be changed with a torch.cuda.device context manager.

device¶ class torch.cuda. device (device) [source] ¶ Context-manager that changes the selected device. Parameters. device (torch.device or int) – device index to select. It’s a no-op if this argument is a negative integer or None.

14.03.2017 · torch.cuda.set_device (device) Sets the current device. Usage of this function is discouraged in favor of device. In most cases it’s better to use CUDA_VISIBLE_DEVICES environmental variable. Parameters: device (torch.device or int) – selected device. This function is a no-op if this argument is negative. next page →

cuda.set_device(). It's possible to set device to 1 and then operate on the tensors on device 0, but for every function internally pytorch would ...

Pytorch’s C++ API provides the following ways to set CUDA stream: Set the current stream on the device of the passed in stream to be the passed in stream. void setCurrentCUDAStream(CUDAStream stream); Attention This function may have nosthing to do with the current device. It only changes the current stream on the stream’s device.

Returns a list of ByteTensor representing the random number states of all devices. set_rng_state. Sets the random number generator state of the specified GPU.

torch.cuda.set_device(device) [source] Sets the current device. Usage of this function is discouraged in favor of device. In most cases it’s better to use CUDA_VISIBLE_DEVICES environmental variable. Parameters device ( torch.device or int) – selected device. This function is a no-op if this argument is negative. Next Previous

Jun 21, 2018 · To set the device dynamically in your code, you can use device = torch.device ("cuda" if torch.cuda.is_available () else "cpu") to set cuda as your device if possible.
