Issue when running GTAnalysis

[chsteel32]

I was starting work on an analysis walkthrough and I encountered an issue when trying to run GTAnalysis using a config.yaml file which was provided with the other files necessary for the analysis. Running the command resulted in a FileNotFoundError which stated that 'conda' was not a valid file or directory. I tried using ipykernel to activate the fermipy environment in jupyter notebook but still had the same error occur. The input and error message are shown below.

gta = GTAnalysis('config.yaml',logging={'verbosity' : 3})

During handling of the above exception, another exception occurred:

Thanks.

Hi @chsteel32 , were you able to resolve this? If you still have this issue, can you please let me know how you installed the fermitools and fermipy?

Please re-open if this is still a problem.
