Error when trying to enable the importer addon in Blender 2.80

When I try to enable the addon for importing the tracking data, Blender 2.80 throws this error:
Traceback (most recent call last): File "C:\Program Files\Blender Foundation\Blender\2.80\scripts\modules\addon_utils.py", line 351, in enable mod = __import__(module_name) File "C:\Users\chris\AppData\Roaming\Blender Foundation\Blender\2.80\scripts\addons\apriltags_import.py", line 2, in <module> import numpy as np File "C:\Users\chris\AppData\Roaming\Python\Python37\site-packages\numpy\__init__.py", line 142, in <module> from . import core File "C:\Users\chris\AppData\Roaming\Python\Python37\site-packages\numpy\core\__init__.py", line 23, in <module> WinDLL(os.path.abspath(filename)) File "C:\Program Files\Blender Foundation\Blender\2.80\python\lib\ctypes\__init__.py", line 356, in __init__ self._handle = _dlopen(self._name, mode) OSError: [WinError 193] %1 is not a valid Win32 application
This also happens on Blender 2.81.

Huh... Weird. I'll look into it.

I just realized it was because I had a bad version of numpy installed. I removed it and now it works.
