Install of Keras and Scipy not completing

Autonomous Machines Jetson & Embedded Systems Jetson Nano

i am trying to install Tensorflow and Keras on the Nano and while I have installed Numpy and Tensorflow ok, I cannot seem to install either Keras or Scipy.

I am using:

sudo pip3 install keras

but get: an error that cetain libraries are missing. Have run apt update and upgrade several times.

/home/jcallum/.local/lib/python3.6/site-packages/numpy/distutils/system_info.py:638: UserWarning:

Any help appreciated.

P.S. I see on another thread that it may be that there are no binaries for keras and scipy and they must be compiled from source? Why would that be I wonder.

Hi,

The issue is that there is no lapack library in your environment.

libraries lapack not found in ['/usr/local/lib', '/usr/lib', '/usr/lib/aarch64-linux-gnu']
NOT AVAILABLE

Could you try to install the library first and try it again?

sudo apt-get update
sudo apt-get install -y build-essential libatlas-base-dev

Thanks.

Thanks. That worked. I was also missing Fortran but now I have installed both scipy and keras.
