Metpy.plots.skewT.plot_barbs
выдает эту ошибку:
TypeError: ufunc 'isfinite' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''
при получении 3 массивов Numpy: pressure
, u
и v
.
Другие пользователи, которые сообщили об этой ошибкесообщение либо не использовало правильный dtype
, либо использовало np
в качестве имени переменной. Я убедился, что ни один из них не является причиной в моем случае. Я также попытался удалить единицы из массивов u и v.
