例如,如果你安装的是CUDA 11.7,可以使用如下命令: pipinstalltorch torchvision torchaudio --extra-index-url 1. 这里的torch,torchvision,torchaudio是PyTorch的主要模块,--extra-index-url指定了PyTorch的预构建包的地址,以确保安装GPU版本。 步骤4:验证安装 安装完成后,打开Python解释器,验证PyTorch是否安装成功,并确...

This API leverages torch.compile to generate a fused FlashAttention kernel, which eliminates extra memory allocation and achieves performance comparable to handwritten implementations. Additionally, we automatically generate the backwards pass using PyTorch's autograd machinery. Furthermore, our API can take...
To install extra dependencies, call pip3 install "torchrl[atari,dm_control,gym_continuous,rendering,tests,utils,marl,open_spiel,checkpointing]" or a subset of these. To install torchrl with the latest pytorch, use pip3 install "torchrl[replay_buffer]" since some features in the replay buffer...
