MSlice hangs or crashes when using the jupyter console #910

Closed MialLewis closed 1 year ago

MialLewis commented 1 year ago

Describe the bug

This occurs on my windows machine (all type of builds), and has been replicated on another windows machine with workbench installed via the installer.

When running scripts the mslice jupyter console takes a long time, hangs, and outputs IOStream.flush timed out

To Reproduce

Run the following script in the mslice Jupyter console (changing the filepath to suit):

import mslice.cli as mc
ws = mc.Load('C:\\MAR21335_Ei60meV.nxs')
wsq = mc.Cut(ws, '|Q|', 'DeltaE, -1, 1')
mc.PlotCut(wsq)
ws2d = mc.Slice(ws, '|Q|, 0, 10, 0.01', 'DeltaE, -5, 55, 0.5')
mc.PlotSlice(ws2d)

Expected behavior The console should work smoothly

@MialLewis Is this not fixed now through Mantid?
