ImportError: libwebp.so.7
See original GitHub issueAfter upgrading holoviews from 1.12.6-py_0 to 1.12.7-py_0 using conda-forge, the following error occurs when I try to use the bokeh backend:
>>> import holoviews as hv
>>> hv.extension("bokeh")
WARNING:param.notebook_extension: Holoviews bokeh extension could not be imported, it raised the following exception: ImportError('libwebp.so.7: cannot open shared object file: No such file or directory')

OS: Ubuntu 19.10 (64-bit)
It seems that libwebp.so.7 is missing in my system, but I can not find a source to install it, it is not available in the Ubuntu packages (only v6) and libwebp v1.1.0 which is available in the conda environment apparently does not provide it either.
Many thanks for your help.
Kind regards,
Axel
