sage: view(B)
I got "==> Fatal error occurred, no output PDF file produced!"
I have tried doing the following inside sage (in my Jupyter notebook) which says the installation was successful.
pip install graphviz
pip install dot2tex
I start to wonder if it is necessary for me to install from source code to be able to do operations in "sage -sh" or "sage -i" to make it work.
I also tried reading 36529, and I was able to reproduce the same issue as in this one, but I could not solve my problem by following it.
Thanks!
