WitrynaConverting Data Type on Existing Arrays. The best way to change the data type of an existing array, is to make a copy of the array with the astype() method.. The astype() function creates a copy of the array, and allows you to specify the data type as a parameter.. The data type can be specified using a string, like 'f' for float, 'i' for integer … Witryna7 mar 2024 · 具体地,代码的每个部分的作用如下: - `image.astype(np.float32)` 将 `image` 数组的数据类型转换为 `np.float32`。 - `np.from_numpy` 将 `numpy` 数组类 …

Witryna19 sie 2024 · Mypy is not aware that changing the dtype of an array changes its annotated type, even if the dtype is passed as a literal np.dtype[np.float64], np.dtype[np.float32], etc. I imagine that this kind of type inference could be very difficult in general, but it would be nice if at least this special case worked. Witrynaa = a.astype(numpy.float32) without copying the array. It is big. The reason for doing this is that I have two algorithms for the computation of a. One of them returns an array of …
