我如何有效地编写Python词典,其中值是numpy nd-arrays to json文件?我会发现一个错误,说numpy nd-array不可用。有什么方法可以克服这一点吗? 看答案 JSON仅支持有限数量的数据类型。如果要将其他类型的数据存储为JSON,则需要将其转换为JSON接受的内容。Numpy阵列的明显选择是将它们存储为(可能是嵌套)列表。幸运的...
fill : int or float or array-like The value(s) for padded borders. If `fill` is numerical type, RGB channels will be padded with single value. Otherwise `fill` must have same length as image channels, which resulted in padding with per-channel values. Returns --- mxnet.nd.NDArray...
mask : array, optional A boolean array used to mark the coordinates in the data that should be analyzed. Has the shape `data.shape[:-1]`. Default: the entire volume, except the edges. Returns --- SpatContFit """ if mask is None: mask = np.ones(data.shape) # Pre-allocate the ...
