libcudart.so.9.0:无法打开共享对象文件：没有此类文件或目录

我在Ubuntu18.04下使用Pytorch并试图导入torchvision，但我得到一个错误libcudart.so.9.0:无法打开共享对象文件：没有这样的文件或目录

有人能帮忙修理吗？谢谢

如果您正在使用anaconda，以下内容可能会解决您的问题

conda install -c anaconda cudatoolkit==9.0

您也可以尝试以下方法

确保CUDA版本为9.0。并将以下两行添加到~/.bashrc

然后，运行：

source  ~/.bashrc

将以下行添加到/etc/ld.so.conf.d/cuda.conf

并运行：

sudo ldconfig

使用以下选项之一检查您的CUDA版本：

 nvidia-smi
 nvcc -V

检查您的Pytorch CUDA版本，如下所示：

 python
 import torch
 torch.version.cuda

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

版本应该匹配。否则，您需要升级/降级您的CUDA或执行相同操作，但Pytorch除外。错误libcudart.so.9.0:无法打开共享对象文件：没有这样的文件或目录意味着版本不匹配。您已经有了针对CUDA 9.0的Pytork，但您的CUDA是另一个版本

要解决此问题，请使用正确的CUDA版本安装Pytorch，如下所示：

 python
 import torch
 torch.version.cuda

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

注：用所需版本替换Pytork和CUDA工具包版本。检查可用版本

如果适用，请重建Pytorch：

 rm -rf build
 python setup.py develop

使用anaconda，火炬版本为：

pytorch==1.1.0
torchvision==0.3.0
cudatoolkit=10.0

具有相同的问题，并通过使用anaconda将torchvision==0.3.0更改为torchvision==0.2.2来修复此问题，torch版本为：

pytorch==1.1.0
torchvision==0.3.0
cudatoolkit=10.0

有相同的问题，并通过将torchvision==0.3.0更改为torchvision==0.2.2来解决此问题。我还没有使用conda，是否需要安装它来解决此问题？不，它只是一种替代方法，在许多情况下对安装环境来说不那么痛苦。只是想知道我是否安装了cuda 10.0，为什么找不到libcudart 9.0？你为CUDA 9.0或10.0安装了Pytork吗？也许我应该为CUDA 10.0重新安装Pytork。我还没有使用conda，有必要安装它来解决这个问题吗？不，它只是一种替代方法，在很多情况下对安装环境来说比较轻松。只是想知道我是否安装了CUDA 10.0，为什么找不到libcudart 9.0？你为CUDA 9.0或10.0安装了Pytork吗？也许我应该为CUDA 10.0重新安装Pytork
