The issue is that in the code below I expect holoviews.save() to generate a .png file but creates a .html file instead
I use holoviews.save() to generate .png files for all sorts of other plots, but it seems like it doesn’t like this type of element. Additionally, this works just fine on my windows machine but not the Linux one which is a bit odd.
import holoviews import holoviews.operation.datashader import datashader.utils import numpy holoviews.extension('bokeh') renderer = holoviews.renderer('bokeh').instance(mode='server') # Create a holoviews.Image ls = numpy.linspace(0, 10, 200) xx, yy = numpy.meshgrid(ls, ls) bounds=(-1,-1,1,1) img = holoviews.Image(numpy.sin(xx)*numpy.cos(yy), bounds=bounds) x_size = 1024 y_size = 768 ds_img = holoviews.operation.datashader.rasterize(img, width=x_size, height=y_size, precompute=True) ds_img = ds_img.opts(width=x_size, height=y_size, cmap='viridis', logz=False, invert_yaxis=True) # Ideally this will create 'ds_img.png' but instead generates a file: 'ds_img.html' holoviews.save(ds_img, 'ds_img.png') # This also doesnt work and fails with an exception. It was something I tried from reading another bug report # datashader.utils.export_image(ds_img, filename='ds_img_ds.png')
