Libcudart. So.9.0: Cannot Open Shared Object File: No Such File or Directory

Question

I'm using Pytorch under Ubuntu 18.04 and trying to import torchvision, but I get an error libcudart.so.9.0: cannot open shared object file: No such file or directory.

Someone could help to fix it? Thanks.

The infos below are detailed error logs:

Accepted Answer

If you are using anaconda, the following may fix your problem.

conda install -c anaconda cudatoolkit==9.0

You can also try the followings.

Make sure the CUDA version is 9.0. And add the following 2 lines to ~/.bashrc.

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

Then, run:

source  ~/.bashrc

Add the following lines to /etc/ld.so.conf.d/cuda.conf

/usr/local/cuda/lib64

And run:

sudo ldconfig

Answer 2

using anaconda, torch version is:

pytorch==1.1.0
torchvision==0.3.0
cudatoolkit=10.0

has the same problem, and fix it by changing torchvision==0.3.0 to torchvision==0.2.2

Answer 3

Check your CUDA version with one of these:
```
 nvidia-smi
 nvcc -V
```

Check your Pytorch CUDA version like this:

 python
 import torch
 torch.version.cuda

The versions should match. Otherwise you need to either upgrade/downgrade your CUDA or do the same but for Pytorch. The error libcudart.so.9.0: cannot open shared object file: No such file or directory means that the versions don't match. You have Pytorch for CUDA 9.0, but your CUDA is another version.

To solve this install Pytorch with the correct CUDA version like this:

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

NOTE: Replace the Pytorch and the CUDA Toolkit version with the desired ones. Check the available versions here.

If applicable, rebuild your Pytorch:
```
 rm -rf build
 python setup.py develop
```
