Can't run predict: doesn't seem to load peak detection parameters from pickle anymore

[yeswecan]

Here's the error inside dill:

Exception has occurred: TypeError       (note: full exception trace is shown but execution is paused at: _run_module_as_main)

TypeError: a bytes-like object is required, not '_io.BytesIO'

Caused by the line

peak_detection_params = dill.loads(io.BytesIO(ckpt['peak_detection_params']))['cpc_1']

I think I got somewhere further fixing this by adding .read to io.BytesIO(ckpt['peak_detection_params']), but it still gives a different error unpickling the same file. Maybe the version of something has changed, but I tried both setting it up via requirements and changing versions of some of the components.
