from fastplotlib.

install fastplotlib directly from main solves the above problem. But I got an error here:
iw.plot.canvas.close()

AttributeError Traceback (most recent call last)
Cell In[9], line 1
----> 1 iw.plot.canvas.close()

AttributeError: 'ImageWidget' object has no attribute 'plot'

When I tested the fastplotlib example, this error came up:

create a Plot instance

plot = Plot()

get a grayscale image

data = iio.imread("imageio:camera.png")

plot the image data

image_graphic = plot.add_image(data=data, name="sample-image")

show the plot

plot.show(sidecar=True)
