problems with display function

[bms1272]

Using Jupyter labs I have had issues with displaying units and systems. Even when I copy example text directly from the website there is an error message even with basic units that work fine with the .show() function.

Hi, thanks for finding this bug. It is now fixed in biosteam==0.9.1.5. Just a heads up, Unit objects are abstract classes for defining a Unit subclass. You can use any of the predefined units (e.g. Mixer, Splitter, Flash, ect.) to simulate unit operations.

If you are still having trouble with displaying unit operations and systems, please try "$conda install graphviz" with administrator privileges on anaconda prompt (or terminal in Mac). Sometimes it is tricky to get it to work. Please checkout the following page for more help: https://bobswift.atlassian.net/wiki/spaces/GVIZ/pages/20971549/How+to+install+Graphviz+software
