Could not resolve ref for gh:fredericfoulonlycee/math_spe_python/master
the repo is :


where the erros is ?could you help me please ? i’m a newbe with binder

Hi! It’s because your default branch is called main, not master. Binder hasn’t yet caught up with the movement of changing the name of the default branch and is still hardcoded to search for master (we’re working on this!). On the mybinder.org Web-form, there is an option to enter a branch name. If you put main in there, it will know to look for the main branch.

thank you very much !
i think it’a a newbie error but i haven’t see it
