Hi!
There was an issue allowing for retracking predicted instances without having to infer the instances again: #260

But it is not working anymore with Sleap v1.2.4.

If the Inference Pipeline Type in the GUI is set to None, and Tracker set to Flow or Simple, it returns with an error that it can run the inference because no Model was specified.

• Versions:
  SLEAP: 1.2.4
  TensorFlow: 2.6.3
  Numpy: 1.19.5
  Python: 3.7.12
  OS: Windows-10-10.0.19041-SP0

• SLEAP installed with Conda from package
