lcopt don't show results_FORWAST_ 500 : Server Error #79

Open R2D2-ad opened 3 years ago

R2D2-ad commented 3 years ago

Hello to everyone! I just set up the environment for lcopt, I launched it and make the example flowchart with the kettle. I did step by step what is showed in the video, however when I click to analyze the results I get an error and no results. I use the FORWAST database. When I go back it works, i can see the flowchart, the parameter set but no results. I attach a screenshot of the error. server_error

I run python 3.8.5 and the browser is Google Chrome. I also launched lcopt by opening the example as it is and still keep having the 'server error 500", no results.

I would appreciate any help. Thanks and best regards

Hello again So after unistall and re-install lcopt, I still have server 500 error and some tracebacks in the powershell listed as followed:

Is something wrong with the brightway2 set up? I am new in all these , so any feedback is welcomed. Thanks again.
