Could not import extension sphinx.ext.imgconverterrecommonmark

[Borda]

Describe the bug

I had problem with SVG images in latexpdf generation so I followed #1907 and added 'sphinx.ext.imgconverter' among extensions but then get this error

py_ImSegm/docs$ make clean ; make latexpdf
Running Sphinx v2.4.0

Extension error:
Could not import extension sphinx.ext.imgconverterrecommonmark (exception: No module named 'sphinx.ext.imgconverterrecommonmark')
Makefile:19: recipe for target 'latexpdf' failed
make: *** [latexpdf] Error 1

To Reproduce
cd docs ; make clean ; make latexpdf

Expected behaviour
having compiled PDF

I guess you're missing a comma after imgconverter. Please check your conf.py carefully!
