{USER}: pi

Install Miniconda 3:

wget http://repo.continuum.io/miniconda/Miniconda3-latest-Linux-armv7l.sh
sudo md5sum Miniconda3-latest-Linux-armv7l.sh # (optional) check md5
sudo /bin/bash Miniconda3-latest-Linux-armv7l.sh # -> change default directory to /home/pi/miniconda3
sudo nano /home/pi/.bashrc # -> add: export PATH="/home/pi/miniconda3/bin:$PATH"
sudo reboot -h now

Test:

conda
python --version

If Conda update miss permission of the directory:

sudo chown -R pi miniconda3

Berryconda worked great for me after experiencing trouble installing some scikit packages with pip and regular conda.

I would like to use Conda - but looking at the problems here I will give a wide berth until is has a more stable and RPi orientated version.

Why not make it completely non-interactive?

echo 'export PATH="/home/pi/miniconda3/bin:$PATH"' >> /home/pi/.bashrc

sudo nano /home/pi/.bashrc # -> add: export PATH="/home/pi/miniconda3/bin:$PATH"

@jjhelmus +1 for Berryconda. My experience is similar (except that it was matplotlib, seaborn, pandas-datareader and pandas).

Hi in my stance, i could install "conda numpy conda" after typing "conda update conda"

hi guys,

Miniconda3-latest-Linux-armv7l.sh is an almost 5 years old version.
Not seen anyone mention this point.

Could someone suggest where to find the latest version please?

thanks @elliptic-porcupine ,

After installed the berryconda, it breaks my PyTorch and installed older Python 3.6
I have to use python3.7 to run my original python 3.7.3

My Raspberry Pi 4 comes with Python 3.7.3 installed.

here is error message.

Could you help please?

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/python3.7",
     and that you have no directories in your PATH or PYTHONPATH that can
     interfere with the Python and numpy version "1.18.1" 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

conda config --set auto_activate_base false
when i tried to use this it throws an error is there any other way to deactivate miniconda?

@loganyc1934 I had the same experience with an older installation of conda, tried updating and had the same experience again. I think the problem is basically that conda packages need to be built specifically for the ARM architecture that RPi uses, and there just aren't many people building them on this architecture. A year or two ago, the situation was better. But nowadays, most of those old builds have disappeared, which means that conda just isn't a good solution for RPi beyond the basic installation of python and pip. In fact, even the most recent installer only installs python 3.4, which is almost 4.5 years old (ancient in conda), and older than the default python3 installed with raspbian.

But the upside is that pip has really improved drastically in recent years. Since I think most of us are using some *nix OS on the RPi, we probably have compilers, and pip is pretty good at compiling things for you automatically. If you need the nice environment management that conda brought, you can now use pipenv. So that's probably the better solution now.

You're right! Miniconda only supports to create env with python 3.4 on Raspi now , I hope I had read your reply before trying it. I have to uninstall Miniconda.

Thanks. I got it

Few days ago, Feb 2nd, Raspberry Pi OS is out of beta. I think it's worth trying official Conda install methods again. I will update this comment with results.
