AttributeError: 'NoneType' object has no attribute 'get'

Trying to check whether the new DiFuMo atlases are now available, I'm consistently hitting this:

In [1]: from templateflow import __version__

In [2]: __version__
Out[2]: '0.7.1'

In [3]: from templateflow.api import get

In [4]: get("MNI152NLin2009cAsym")
---------------------------------------------------------------------------

     66     ]
     67

AttributeError: 'NoneType' object has no attribute 'get'

Happened with master, 0.7.1 and 0.6.3.

I'm sure it is a problem with my installation / have pip uninstalled and installed and I have deleted ~/.cache/templateflow.

We need to figure this one out ASAP, and also try to understand the extent to which this is happening.

BTW, the tests are broken, so this could easily have been masked by a failing (unrelated) test.

Before the release of fMRIPrep 21.0.0rc1 we need to have this one pinned down and towards a bugfix.

cc/ @effigies as this may complicate the rc1 release.

my guess is something is going wrong when initializating your layout here

https://github.com/templateflow/python-client/blob/137218d01f5edc5c75092decda51e369fd4d3692/templateflow/conf/__init__.py#L89-L115

I tried:

• fresh environment (Python 3.9.4 [Clang 12.0.5 (clang-1205.0.22.9)] on darwin)
• deleted ~/.cache/templateflow
• replicated your ipython calls

Cannot reproduce, so I assume this is something going on with your installation

Yes, found it - I have miniconda, and then pip installed pybids. The problem is that pip didn't seem to correctly install sqlalchemy correctly. Only after installing it through conda it worked.

We need to change that try .. catch, or at the very least make it more specific to only pybids. One solution would be to import bids again inside get() and get_templates().
