Albacore wheel not supported on this platform (Mac OS X El Capitan)

Question

I download the Albacore wheel from Oxford Nanopore.

I activated my conda environment that has Python 3 as the default python version.

I tried to install Albacore with

pip3 install ont_albacore-2.1.10-cp36-cp36m-macosx_10_11_x86_64.whl

but got the following error:

ont_albacore-2.1.10-cp36-cp36m-macosx_10_11_x86_64.whl is not a supported wheel on this platform.
You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.`

I then upgraded my pip with:

pip install --upgrade pip
Requirement already up-to-date: pip in /Users/.../anaconda3/envs/python3env/lib/python3.6/site-packages`

So it seems that my pip was already up to date. I do not understand why it complains about my pip if I am using pip3 anyways. I tried to install Albacore again but I got the same message as before.

Can anyone help me install Albacore on my Mac El Capitan laptop, please?

Update based on Wouter's suggestion:

python -m pip install ont_albacore-2.1.10-cp36-cp36m-macosx_10_11_x86_64.whl

At first sight, it looks like Albacore was successfully installed but if I run: read_fast5_basecaller.py --help

I get:

Is there a library missing?

Answer 1

Not sure about conda as I don't use it, but I can highly recommend pipenv which is the python.org recommended package management system for python.

I have tested the following on my Mac and it worked like a dream

mkdir albacore && cd albacore
mv ../ont_albacore-2.1.10-cp36-cp36m-macosx_10_11_x86_64.whl .

# install pipenv if you don't have it
brew install pipenv  # or pip3 install pipenv

# the following will create a virtual environment and install albacore into it
pipenv install ont_albacore-2.1.10-cp36-cp36m-macosx_10_11_x86_64.whl

# activate the virtual environment
pipenv shell

read_fast5_basecaller.py -h

And that should bring up the albacore help menu and you're ready to go.
