Hello everybody,
While adding some tests to a project of mine, I noticed some really weird behaviour. Two different instances initialised with the same parameters (including random_state) output a different result for fit_transform during an execution. But when running the program again, the output does not change.
Am I missing something obvious? Or has anybody an idea why this is happening.
Thanks for looking into it.
