My goal is to use Numpy inside of Anaconda on the Raspberry Pi 3B. I downloaded Anaconda by following the instructions: https://stackoverflow.com/questions/49170125/cannot-install-anaconda-in-raspberry-pi-3. Then

pi@raspberrypi:~ $ conda install anaconda-client
pi@raspberrypi:~ $ conda create -n condaVEnv00 python=3
pi@raspberrypi:~ $ source activate condaVEnv00
(condaVEnv00)pi@raspberrypi:~ $ conda install anaconda-client
(condaVEnv00)pi@raspberrypi:~ $ conda install numpy
Fetching package metadata: ....
Solving package specifications: 
Error: Could not find some dependencies for numpy: blas * openblas

You can search for this package on anaconda.org with

    anaconda search -t conda blas * openblas
(condaVEnv00)pi@raspberrypi:~ $ anaconda search -t conda blas * openblas
usage: anaconda [-h] [--show-traceback] [--hide-traceback] [-v] [-q] [--color]
                [--no-color] [-V] [-t TOKEN] [-s SITE]
                COMMAND ...
anaconda: error: unrecognized arguments: current Desktop Documents Downloads MagPi miniconda3 Miniconda3-latest-Linux-armv7l.sh Music Pictures Public Templates Videos openblas

How can I proceed to implement Numpy in the Anaconda environment?

miniconda doesn't appear to support python>=3.5 on arm71, and current numpy installs all appear to need python>=3.5. Instead you can use the apt-get install, the pip install doesn't seem to work.

sudo apt-get install python3-numpy

As stated in the link that you provided, you should use Miniconda. The default installed channel (pkgs/free) has very limited capabilities, and the RPi channel is better. To add that, run

conda config --add channels rpi

from the command line.

This will add the channel. Then you can run installation commands such as

conda install numpy

Enjoy!

I got much of the information from GitHub: simoncos/miniconda_on_rpi.md.
