Вопрос:
Почему sklearn не может обнаружить зависимость от liblapack и как это исправить?Справочная информация:
Я использую следующую среду conda (torch-nightly) с установленным scikit-learn (обратите внимание, что также существует зависимость от liblapack):(torch-nightly) au@a2 ~ % conda list |grep "scikit-learn"
scikit-learn 1.1.1 py38hc377ac9_0
(torch-nightly) au@a2 ~ % conda list |grep "liblapack"
liblapack 3.9.0 15_osxarm64_openblas conda-forge
Проблема:
При попытке импортировать sklearn я получаю следующую ошибку:(torch-nightly) au@a2 ~ % python -c "import sklearn"
