Я начал изучать Tensorflow. Я использую Pycharm и моя среда Ubuntu 16.04. Я следую учебнику . Я скрещиваю чек. Это актуально. Я не знаю причину этой ошибки.
из numpy.lib.arraypad import _validate_lengths
ImportError: невозможно импортировать имя '_validate_lengths'
Нужна подсказка для устранения этой ошибки. Спасибо.
