#Hi, ezTrack is a pretty cool and straightforward tool. #we can successfully install it when we follow the README file. but when we tried to run the code in jupyter notebook, we came across the error below:

Did you follow the install instructions exactly? Is the correct conda environment activated? From the error report it looks like this is an issue with loading package dependencies, rather than anything with ezTrack itself.
