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...
3. `arr` is an array of arrays of different shapes. Returns `arr`. 4. Items in `arr` are not ndarrys or scalars. Returns `arr`. Parameters --- arr : array, dtype=object The array to be converted. mask : array, dtype=bool, optional Where arr has Nones. fill : number, optiona...

A Python library for manipulating indices of ndarrays. The documentation for ndindex can be found athttps://quansight-labs.github.io/ndindex/ ndindex is a library that allows representing and manipulating objects that can be valid indices to numpy arrays, i.e., slices, integers, ellipses, ...
这与这个关于NumPy arrays的问题非常相似,对于这个问题,公认的答案i.e., for i in range(z.shape[-1]): print(z[..., i]) 也适用于PyTorch张量。 您提供的最后一种方法是干净高效的。它直接访问沿最终维度的每个切片,而不需要显式排列。它也适用于PyTorch张量。

To keep any addition of compiled code to a minimum, the basic approach followed by most of the methods implemented in this PR is to utilise NumPy's ravel/unravel and reshape tools to map n-D arrays to 2-D and use the pre-existing CSR sparsetools. Since COO allows for quick conversion...
