Thank you for the detailed information! One word of advice, though: you probably still have the connection to the database open at this point. Closing the connection via |

scenario.solve() is notebook cell 28, but to solve the problem, I repeatedly ran the cell, which caused the cell number to change。 However, I have this file on my local machine. to solve the problem,i run the cell again,then the error mentioned above occurred （This Scenario must be checked in before performing this operation when run scenario.solve()）. specific details of the error when first run：

Thanks for the explanation, so extra code doesn't seem to be the problem. Now I notice something else, though: in the output of ixmp: 3.7.0

If the above does not help, I remember that there were issues with installations on macOS in the past, specifically this issue, though the fixes found there made their way into the official install instructions already. However, the fix included NOT using anaconda, if I remember correctly, so maybe there is an issue with anaconda and homebrew. If you are not using it for something else, could you please try uninstalling anaconda and then follow these steps:
The above steps are tested for M1Pro processor. Ensure that GAMS, JAVA, Python are all channel URLs:
