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

[Rachel Ilan Ehrenfeld]

Hi,

I'm new to Keras and new to Ubuntu. I follow the instructions on the end of the book "Deep learning with Python" by Francois Chollet to install on my computer the Keras with all the other things. I arrive to the final step - testing my installation by typing in: python examples/mnist_cnn.py and get the following error:

~/keras$ python examples/mnist_cnn.py

Using TensorFlow backend.

I'm not familiar with this particular tutorial, but was there a step to install Tensorflow and make sure that was installed prior to running the code you posted?

Thanks,

More importantly, assuming one wants to use a GPU, then you need to install tensorflow-gpu and CUDA 9.0, and you have to make sure that paths to CUDA are set correctly.

 

You also have to install exactly CUDA 9.0 as currently the tensorflow binaries are linked to that version, not 9.1 or 9.1.
