I've been using pyinstrument for a while.

The biggest problem with the standard profiler is that the reported times are not split by code path. For example, if you have two parts of your code that call the same library function, and you want to know which path is the slow path...you can't. The time reported for each line is a sum of all times/paths it was called. Worse, the visualization tools don't hint that this is the case, so you end up with very incorrect plots. Pyinstrument will give you the time, by path. Super useful, and a huge time saver!
