ImportError: libcusolver.so.8.0: cannot open shared object file: No such file or directory

Question

Possible duplicate of this question. I have a gpu account to whom I connect through putty (ssh login). I have created a virtualenv there and I am installing tenorflow through pip for gpu. Everything works fine, when I run command

$ pip list

following list is being shown:

 backports.weakref (1.0rc1)
 bleach (1.5.0)
 funcsigs (1.0.2)
 html5lib (0.9999999)
 Markdown (2.6.8)
 mock (2.0.0)
 numpy (1.13.1)
 olefile (0.44)
 pbr (3.1.1)
 Pillow (4.2.1)
 pip (9.0.1)
 protobuf (3.3.0)
 setuptools (36.0.1)
 six (1.10.0)
 tensorflow-gpu (1.2.1)
 Werkzeug (0.12.2)
 wheel (0.29.0)

But when I run:

$ python
>>> import tensorflow

It shows the following error:

  Traceback (most recent call last):

  ImportError: libcusolver.so.8.0: cannot open shared object file: No such

  Failed to load the native TensorFlow runtime.
  See https://www.tensorflow.org/install/install_sources#common_installation_problems
  for some common reasons and solutions.  Include the entire stack trace
  above this error message when asking for help.

I have also set my environment variables like this:

  export CUDA_HOME=/opt/cuda
  export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$CUDA_HOME/lib64:$CUDA_HOME/extras/CUPTI/lib64"

Moreover, I found that libcusolver.so.8.0 is not there, while libcusolver.so.7.5 is there in cuda/lib64/. Somehow tensorflow is finding wrong file or I ain't know nothing. Any help would be appreciated as I am new to all this stuff. Python version: 2.7 OS: Linux

Solution 1

I solved the issue. Actually I have cuda 7.5 installed and I was installing latest tensorflow version which probably support cuda 8.0. So I downgraded.

 pip install --upgrade \ https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.10.0-cp27-none-linux_x86_64.whl

Solution 2

This may be connected to the incorrect linking of your libraries.
Simply run sudo ldconfig /usr/local/cuda/lib64. It solved for me.

If you need to know more: ldconfig man page.

I also just installed tensorflow version 1.2.0 instead of 1.3.0 to use cuda 7.5 with pip install tensorflow==1.2.0. Note that I left tensorflow-gpu at 1.3.0

@ben26941 my guess is that you are using cuda-9.0 . In that case try sudo apt install nvidia-cuda-dev (if you are using an Ubuntu distribution)
