Hello, currently python-scikit-learn fails to build in f40 and rawhide https://bugzilla.redhat.com/show_bug.cgi?id=2261602 The problem is a series of incompatible pointer conversions that appear in cython generated C code. The code has classes defined in cython and in the offending code "self" is passed as a pointer to the base class with a conversion to the derived class sklearn/metrics/_dist_metrics.c: In function ‘__pyx_f_7sklearn_7metrics_13_dist_metrics_19EuclideanDistance32_dist_csr’: sklearn/metrics/_dist_metrics.c:51033:90: error: passing argument 1 of ‘__pyx_f_7sklearn_7metrics_13_dist_metrics_19EuclideanDistance32_rdist_csr’ from incompatible pointer type [-Wincompatible-pointer-types] note: expected ‘struct __pyx_obj_7sklearn_7metrics_13_dist_metrics_EuclideanDistance32 *’ but argument is of type ‘struct __pyx_obj_7sklearn_7metrics_13_dist_metrics_DistanceMetric32 *’ Regards, Sergio -- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
