Python 3.10 issues
When I try to load a file in katrain with CTRL-L the file list is empty, also I cannot change the folder. In the info window I get the following error:
ERROR: Exception AttributeError: "module 'collections' has no attribute 'Callable'" File "kivy/_clock.pyx", line 645, in kivy._clock.CyClockBase._process_events File "kivy/_clock.pyx", line 218, in kivy._clock.ClockEvent.tick File "/usr/lib/python3.10/site-packages/kivy/uix/filechooser.py", line 711, in _update_files if self._create_files_entries(): File "/usr/lib/python3.10/site-packages/kivy/uix/filechooser.py", line 731, in _create_files_entries index, total, item = next(self._gitems_gen) File "/usr/lib/python3.10/site-packages/kivy/uix/filechooser.py", line 852, in _generate_file_entries for index, total, item in self._add_files(path): File "/usr/lib/python3.10/site-packages/kivy/uix/filechooser.py", line 879, in _add_files files = self._apply_filters(files) File "/usr/lib/python3.10/site-packages/kivy/uix/filechooser.py", line 668, in _apply_filters if isinstance(filt, collections.Callable):
My system is Arch Linux with kernel 5.15.13-arch1-1 Python version 3.9
Looks like python 3.10 - and kivy doesn't seem very happy with it in several ways. I've submitted a fix for this particular thing, but it might take a while to be fully compatible. In the mean time, I recommend using a py3.8 or 3.9 based venv.
Another python 3.10 issue reported on discord was:
ImportError: "/home/b2/katrain/lib/python3.10/site-packages/kivy/_event.cpython-310-x86_64-linux-gnu.so: undefined symbol: _PyGen_Send
I can confirm that running in a virtual environment with python 3.9 solves the problem. So I think the problem lies with kivy. I think you can close the bug here.
Another 3.10 issue

Using a 3.9 venv solves all the issues for now
pyenv install 3.9.7
pyenv shell 3.9.7
pip3 install -U katrain
# install kivy from source
git clone git://github.com/kivy/kivy.git
cd kivy
python -m pip install -e ".[dev,full]"
The packaged version still has the same problem. That installed in a venv is working good.
