When I install mmcv-full ==1.3.14, there's an importError: libcudart.so.10.2

[ggomac]

I have searched related issues but cannot get the expected help.

my environment GPU : GeForce RTX 3080 cuda version 11.1 pytorch 1.9.0

When I install mmcv-full =1.3.14 there's an import error : libcudart.so.10.2: cannot open shared object file

When I changed the mmcv-full version =1.3.13, the error was solved.

Why this error occurred?

hi, what command did you use to install mmcv-full?

I used this command

pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9.0/index.html

Could you provide the following environments?

echo $PATH
echo $LD_LIBRARY_PATH

[zhouzaida]

please check whether the CUDA/GCC runtimes are the same as those used for compiling mmcv.

cuda 11.1

please check whether the CUDA/GCC runtimes are the same as those used for compiling mmcv.

cuda 11.1 gcc 9.3.0

I think it doesn't have connection with cuda version or python version. @zhouzaida

python 3.8 cuda 10.2 mmcv-full 1.3.13

[zhouzaida]

hi, @459737087. It seems like that mmcv was complied in cuda10.1 but is called in cuda10.2. You can print the dependencies of mmcv/_ext.*so by ldd mmcv/_ext.*so
