Installation issue -- parso requires Python >=3.6

[TayteCampbell]

When I try and install sourcetracker2 using the regular 'pip install sourcetracker' command I get the error message:

parso requires Python '>=3.6' but the running Python is 3.5.6 You are using pip version 10.0.1, however version 20.3.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command.

This results in sourcetracker2 not being installed.

I have tried updating the pip version within this conda environment using 'pip install --upgrade pip' and then trying to reinstall sourcetracker2 with 'pip install sourcetracker'

This results in the installation of sourcetracker2 but when I try to run 'sourcetracker2 gibbs --help' I get the following error:

node_map: Dict[str, type] = {}
        ^

SyntaxError: invalid syntax

I've found that I can get it to work if I just do the following:

conda create -n st2 conda activate st2 pip install sourcetracker

Is this alteration in the installation going to cause issues?

As mentioned in the official page of the project parso, the 0.7.1 version is the latest version supporting python 3.5:

0.7.1 (2020-07-24)

Fixed a couple of smaller bugs (mostly syntax error detection in Grammar.iter_errors)

This is going to be the last release that supports Python 2.7, 3.4 and 3.5.

I typed pip install parso==0.7.1 before running pip install sourcetracker in the conda environment "st2". Here is the notification I got:

Successfully built sourcetracker mkl-random 1.0.1 requires cython, which is not installed.

and I then typed pip install cython, it seems to be resolved:

Successfully installed cython-0.29.21.

I just successfully installed by placing python=3.5 with python=3.6. Seems to be working fine.

conda create -n st2 -c biocore python=3.6 numpy scipy scikit-bio biom-format h5py hdf5 seaborn
conda activate st2
pip install sourcetracker

Thank you, this installation seems to have worked
