我在Ubuntu 18.04下使用Pytorch，并尝试import torchvision，但我得到了一个错误libcudart.so.9.0: cannot open shared object file: No such file or directory。
有人能帮忙修吗？谢谢。
以下信息是详细的错误日志：

如果您使用的是anaconda，下面的方法可以解决您的问题。

conda install -c anaconda cudatoolkit==9.0

您还可以尝试以下操作。
确保CUDA版本为9.0。并将以下2行添加到~/.bashrc。

export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

然后，运行：

source  ~/.bashrc

将以下行添加到/etc/ld.so.conf.d/cuda.conf

/usr/local/cuda/lib64

并运行：

sudo ldconfig

使用anaconda，torch版本为：

pytorch==1.1.0
torchvision==0.3.0
cudatoolkit=10.0

存在相同的问题，请通过将torchvision==0.3.0更改为torchvision==0.2.2来解决该问题

1.使用以下方法之一检查您的CUDA版本：

nvidia-smi
 nvcc -V

1.检查您的Pytorch CUDA版本，如下所示：

python
 import torch
 torch.version.cuda

1.版本应该匹配。否则，您需要升级/降级CUDA或对Pytorch执行相同操作。错误libcudart.so.9.0: cannot open shared object file: No such file or directory表示版本不匹配。您的Pytorch是CUDA 9.0，但CUDA是另一个版本。
1.要解决这个问题，请使用正确的CUDA版本安装Pytorch，如下所示：

conda install pytorch==1.2.0 torchvision==0.4.0 cudatoolkit=10.0 -c pytorch

注意：将Pytorch和CUDA Toolkit版本替换为所需版本。检查可用版本here。
1.如果适用，重新构建Pytorch：

rm -rf build
 python setup.py develop

尝试以下命令

pip3 install torch===1.2.0 torchvision===0.4.0 -f https://download.pytorch.org/whl/torch_stable.html

我正在使用CUDA版本：11.6，这解决了我的错误。

下面是一个独立于cuda版本的通用解决方案。
1.目标是设置到cuda库（称为libcudart.so.<version number>）的正确路径。
1.我们通过sudo find / -name 'libcudart.so.<version number>'求出这条路径
1.我们必须在.bashrc中添加包含libcudart.so.<version number>的文件夹（而不是文件）的路径：
export LD_LIBRARY_PATH=<path to libcudart.so file>:$LD_LIBRARY_PATH

pytorch 软件库9.0：无法打开共享目标文件：无此文件或目录
