python 3.x - ImportError: libcublas.so.9.0: cannot open shared object file

Question

currently I have cuda 8.0 and cuda 9.0 installed in Gpu support system. I ran into this error while importing from keras module. It says like failed to load native tensorflow runtime. The error log which i received was:

Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/pywrap_tensorflow.py", line 58, in <module>

return load_dynamic(name, filename, file)
File "/usr/lib/python3.5/imp.py", line 342, in load_dynamic
return _load(spec)

ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

When I run nvcc --version, the cuda version returned is,

Cuda compilation tools, release 8.0, V8.0.61

I read about some similar post but couldn't solve my issue. Mostly I think this is a clash between two cuda versions. Can anyone tell me how to solve this? Thanks in advance.

You will need to update your LD_LIBRARY_PATH, so that it points to the /usr/local/cuda-9.0/lib64. Add the following line to your .bashrc file (or any other terminal you use)

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-9.0/lib64/
