Hello! I'm running Ubuntu20, python3.8 and ran into an issue attempting to load a tdag.
Steps to Reproduce
I cloned the newest version of polytracker from this repo, cd'd to it and installed via pip3 install ./.
I then attempted to load the tdag database, which led to a KeyError:
output$ python3

KeyError: <class 'polytracker.taint_dag.TDSourceSection'>
I verified this key does exist in the taint_dag class:
Overall, I want to use the github version of PolyTracker so that I can leverage the new code additions; namely, retrieving labels via polytracker.taint_dag.TDFile.input_labels and using those to pass off to additional analysis

Thanks for using PolyTracker!
From the trace you added it seems like there is no TDSourceSection in the tdag-file. This situation deserves a better error message.
It looks like there might have been an issue with how the tdag-file was generated. Could you please share the steps used to generate the tdag?
I had a version mismatch between the older docker image, tried building outside of it. After updating acropalypse's Dockerfile to also include the URL for libpng, I ran the pngtest, copied the tdag outside of the docker image and got it working. I'm going to close as this was a potato on my end.
By the way, thanks for all of the dev, tooling and support over the years!
