I gets the following error (python 3.8.3)
File "thdg.py", line 19, in <module> from yaml import CLoader as Loader, CDumper as Dumper, load, dump ModuleNotFoundError: No module named 'yaml'
I needed to install pyyaml too.
Oh, that's right! I'd better mention that.
To clarify, you get that error after you installed pyyaml? Or did installing pyyaml fix your problem?
Fixed it, works 100% after installing pyyaml.
