Новое для Scipy.scipy.test() терпит неудачу со многими ошибками утверждения
Я установил scipy и numpy, но ween Я запускаю scipy.test() Я получаю много тестов. Я пытался найти некоторые общие причины, и я нашел несколько:
>>> import scipy
>>> scipy.test()

Звуки для меня, как проблема MPI или что-то, но я would't знаю.
Любая помощь была бы принята с благодарностью.
Лучший, Джонатан.
-------- EDIT --------- Пробовал его с помощью scipy.test (verbose = 10). Большинство тестов, похоже, работают нормально. Сбой начинается с ОШИБКИ. это то, что я получаю:

Мне очень жаль, что я понятия не имею, что означают ошибки.
кажется, что numoy терпит неудачу, а также. Проблема в том, что она ожидает 7-8 цифр после десятичной точки, тогда как она получает точность 3. Любая идея? Я думал, что это может быть компилятор Fortran, но я думаю, что numpy не использует Fortran. –
Ошибки Scipy кажутся типичными для того, что получается из-за неправильной (= ABI несовместимости с Veclib) компилятором Fortran на OSX. Любые ошибки Numpy, скорее всего, не связаны с ними - трудно сказать, не видя их. Вы можете найти их полезными: http://projects.scipy.org/scipy/ticket/1476 http://projects.scipy.org/scipy/ticket/1496 –
