Inline images not appearing
Opened this issue · 0 comments

I am trying to display inline graphics in ob-ipython. I can display them successfully in the browser in a jupyter notebook. I can also display R graphics inline in org-babel.
With :ipyfile
header, no graphic appears. With :file
header, an empty image box appears in the results.
I get the same result when exporting to HTML: no output from ipython, yes output from R.
