Cannot convert numpy types to json (numpy 2.0)

[hyanwong]

When printing the output of the HmmRun class, using asjson(), here:

sc2ts/sc2ts/cli.py

Line 761 in 89421fb

return d

I'm getting "TypeError: Object of type int64 is not JSON serializable". I think this is because numpy 2 saves e.g. integers and float as special types that are not directly convertible to JSON. To get it to work, I had to adjust the asdict() method to use .item() to convert two of the values:

        d["match"]["cost"] = d["match"]["cost"].item()
        d["match"]["likelihood"] = d["match"]["likelihood"].item()
