2 years ago a couple of things that might help you
- You can set the PMIP_CBC_LIBRARY env var to point to the binary you want to use.
- Stable versions of CBC seem to not work (https://github.com/coin-or/python-mip/issues/165) so you will probably want to compile CBC master from source (e.g. https://github.com/coin-or/python-mip/issues/165#issuecomment-1058946026)
Background: When using the 1.13.0 release, my code runs fine. However when using the current version on master with new CBC binaries, CBC crashes (after the timelimit is reached but before returning to python).
In order to investigate this issue I would like to test my code with more different versions of CBC. It is clear to me that the binaries are located in python-mip\mip\libraries. With a single "cbc-c-linux-x86-64.so" of around 20MB for linux. However, when downloading the compiled releases from https://github.com/coin-or/Cbc/releases I can't seem to find a large monolithic .so file anywhere in the archive.
Question: Where can I find instructions on how to use custom binaries for python-mip?
