在Ubuntu上安装PyTorch可能会遇到一些问题,但大多数问题都可以通过以下步骤解决:
sudo apt update
sudo apt install python3 python3-pip
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh
source ~/.bashrc
wget https://repo.anaconda.com/archive/Anaconda3-2023.07-2-Linux-x86_64.sh
bash Anaconda3-2023.07-2-Linux-x86_64.sh
source ~/.bashrc
python3 -m venv pytorch_env
source pytorch_env/bin/activate
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu
pip3 install torch torchvision torchaudio
conda create -n pytorch_env python=3.8
conda activate pytorch_env
conda install pytorch torchvision torchaudio cpuonly -c pytorch
conda install pytorch torchvision torchaudio cudatoolkit=11.7 -c pytorch
在Python解释器中运行以下代码来验证PyTorch是否安装成功:
import torch
print(torch.__version__)
print(torch.cuda.is_available()) # 应该返回True,如果CUDA可用
如果在安装过程中遇到具体的错误信息,请提供详细的错误信息,以便进一步诊断和解决。
