How do I install Keras on arm64, Ubuntu 16.04?

Question

I tried pip install --user keras==1.0.6 but it fails to build scipy. It returns:

numpy.distutils.system_info.NotFoundError: no lapack/blas resources found

and

failed with error code 1 in /tmp/pip-build-XjG1HN/scipy/ .

I also tried installing scipy alone, using these instructions :

export PATH="$PATH:/home/your_user/.local/bin"
pip install --user scipy

But received the same errors.

Note: While posting this I realized I didn't replace your_user with $USER . However, I found a different solution, see answer below.

Answer 1

sudo apt-get install python-scipy

This successfully installed scipy on an arm64 Ubuntu 16.04 (on NVIDIA's Jetson TX1 with Jetpack 2.3).

The additional packages include lapack and blas packages, which the error alluded to.

The following additional packages will be installed: lib blas -common lib blas 3 libgfortran3 lib lapack 3 python-decorator python-imaging python-numpy python-pil

And then to install keras 1.0.6:

pip install --user keras==1.0.6

I found this answer by googling "install scipy "arm64"" and finding Xenial (16.04) : python-scipy package : Ubuntu - Launchpad .
