memory error

[Julien Gautier]

hi

I have sometime a memory error when i using setImage

this is an example of my code :

self.Image=pg.GrraphicsLayoutWidget()

self.p1=self.winImage.addPlot()

self.imh=pg.ImageItem()

self.p1.addItem(self.imh)

while true :

self.imh.setImage(data.astype(float),autoLevels=True,autoDownsample=True)

and the error:

MemoryERROR: 

traceback(....)

file "./pyqtgraph/graphicsItems/ImageItem" , inn paint

self.render() 

Thanks

in fact the error is the following :

Traceback (most recent call last):

self.render()

MemoryError

A MemoryError indicates you're out of memory for some reason, so the traceback may not be all that helpful in determining why it's happening (np.clip may just happen to be where numpy tried to allocate some memory and failed). A more complete example that reproduces the error would be helpful, but I understand if that's not feasible (problem may go away outside the context of the bigger application). Any additional information on the structure of your program and how you're generating data would be useful in figuring out what's going on. It also couldn't hurt to have the output of `conda list` as well.
