Cannot iterate over keys of a variable in 0.18.4 #2007
Comments
Can you test on |
Some update about this issue ? I got the same problem when I have tried to use: |
This is fixed in JuMP 0.19 onwards. Can you update? |
Thanks for your return, but I cannot update because Clp is not compatible with new versions of JuMP. |
Clp is not compatible yet to JuMP v0.20 but it is compatible with JuMP v0.19 |
Closing as out-dated. We won't be fixing this in 0.18, and it is fixed in JuMP 0.21. |
