Importing antspynet error

[celstark]

Describe the bug Error importing antspynet. Install is from either pip or from github source (same error)

To Reproduce

(base) stark@Titan:~$ conda activate antspy
(antspy) stark@Titan:~$ python

Expected behavior No error

Desktop (please complete the following information):

• Ubuntu 20.04
• Python 3.9
• Clean install in new environment

Other I've also tried building up a totally clean singularity image based on Ubuntu 18.04 & miniconda-latest and having it only install antspyx and antspynet in here. Same error. Relevant bit from singularity recipe (derived from neurodocker):

export PATH="/opt/miniconda-latest/bin:$PATH"
echo "Downloading Miniconda installer ..."
conda_installer="/tmp/miniconda.sh"
curl -fsSL --retry 5 -o "$conda_installer" https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash "$conda_installer" -b -p /opt/miniconda-latest
rm -f "$conda_installer"
conda update -yq -nbase conda
conda config --system --prepend channels conda-forge
conda config --system --set auto_update_conda false
conda config --system --set show_channel_urls true
sync && conda clean -y --all && sync
conda install -y -q --name base \
    "pip"
sync && conda clean -y --all && sync
bash -c "source activate base
  pip install --no-cache-dir  \
      "antspyx" \
      "antspynet""

Runtime:

I'm guessing it's a Python 3.9 issue.

That'd been my thought too -- did a singularity based on a Python 3.7 (https://repo.anaconda.com/miniconda/Miniconda3-py37_4.9.2-Linux-x86_64.sh) and we seem good.
