I have installed pyomo in anaconda in an oemof environment.
Can you outline the steps you have undertaken for this?
Spyder normally uses Anacondas ‘default’ environment. If you have created another one for the installation oemof, pyomo, etc. these packages cannot be found in the ‘default’ env. You either have to activate the specific environment our you could use Anacondas default environment (among other options).
Thanks for your explanation. Then, I think it will be related to Spyder and IPython/Jupyter I guess. As I am not using Spyder as an editor I cannot check it myself but google lists a lot of pages about a not working autocompletition in Spyder/Jupyter.
During the time when I had used Spyder I have made good experiences with Spyders’ github project and put my questions there. One of the main developers (Carlos Cordoba) replies quite quickly. He is also active on stackoverflow so both channels might be useful.
