Unable to start ledfx

[theSC]

Raspbian Buster-lite.

Installing ledfx seems to have succeeded but upon trying to start ledfx I get the following errors:

Traceback (most recent call last): File "/home/pi/.local/lib/python3.7/site-packages/numpy/core/init.py", line 17, in from . import multiarray File "/home/pi/.local/lib/python3.7/site-packages/numpy/core/multiarray.py", line 14, in from . import overrides File "/home/pi/.local/lib/python3.7/site-packages/numpy/core/overrides.py", line 7, in from numpy.core._multiarray_umath import ( ImportError: libf77blas.so.3: cannot open shared object file: No such file or directory

During handling of the above exception, another exception occurred:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions failed.

• Try uninstalling and reinstalling numpy.

• If you have already done that, then:

  1. Check that you expected to use Python3.7 from "/usr/bin/python3", and that you have no directories in your PATH or PYTHONPATH that can interfere with the Python and numpy version "1.17.4" you're trying to use.
  2. If (1) looks fine, you can open a new issue at https://github.com/numpy/numpy/issues. Please include details on:
     • how you installed Python
     • how you installed numpy
     • your operating system
     • whether or not you have multiple versions of Python installed
     • if you built from source, your compiler versions and ideally a build log

• If you're working with a numpy git repository, try git clean -xdf (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes, so please don't comment on an existing issue about this - open a new one instead.

Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory

Anything?

Would still love any help someone could give me. This is a fresh install of the OS and ledfx with nothing else. I am at a loss as to what to do

Are you trying to install on RaspberryPi? Have you tried following the instructions here? #62

[theSC]

Yes I am using a RaspberryPi. The linked instructions fail for me at conda create -n ledfx. I get "illegal instruction"
