heatmaps do not work

[anshvarts]

It is the issue from ECEM workshop

File "/Applications/anaconda/lib/python2.7/site-packages/spyder/utils/site/sitecustomize.py", line 880, in runfile
execfile(filename, namespace)

File "/Applications/anaconda/lib/python2.7/site-packages/spyder/utils/site/sitecustomize.py", line 94, in execfile
builtins.execfile(filename, *where)

File "/Users/AShvarts/Documents/pyton/ECEMWorkshop/afternoon/analysis_mine.py", line 145, in
savefilename=plotpath)

File "pygazeanalyser/gazeplotter.py", line 227, in draw_heatmap
heatmap[y:y+gwh,x:x+gwh] += gaus * fix['dur'][i]

TypeError: slice indices must be integers or None or have an index method

Solved! You need to add int() into the line 227 of gazeplotter.py
Instead: heatmap[y:y+gwh,x:x+gwh] += gaus * fix['dur'][i]

You should have: heatmap[int(y):int(y+gwh),int(x):int(x+gwh)] += gaus * fix['dur'][i]

It works for me!

I also have a problem with the function, though it is another error:

_/content/gazeplotter.py in draw_display(dispsize, imagefile)
408 # draw the image on the screen
409 screen[y:y+h,x:x+w,:] += img
--> 410 # dots per inch
411 dpi = 100.0
412 # determine the figure size in inches
