ImportError: libcudart.so.7.0: cannot open shared object file: No such file or directory

When I execute python command, a "ImportError" error occurs.Some solved it by adding "export LD_LIBRARY_PATH=/usr/local/cuda-5.5/lib:/usr/local/cuda-5.5/lib64" in the /etc/profile.I try it but do no effect.I find the "libcudart.so.7.0" in /usr/share/man/man7/libcudart.so.7 by executing the whereis command and have no idea what should I do next to solve it.

Answer 1

This error is being raised because the loader cannot find version 7.0 of the CUDA runtime on your system. TensorFlow requires CUDA 7.0.

From the path in your question (/usr/local/cuda-5.5/...) it looks like you have CUDA 5.5 installed. The solution is to upgrade your CUDA runtime to version 7.0, which is available from NVIDIA here.
