numpy.lib.format.read_array_header_1_0

lib.format.read_array_header_1_0(fp, max_header_size=10000)[source]

Read an array header from a filelike object using the 1.0 file format version.

This will leave the file object located just after the header.

Parameters:

fpfilelike object

A file object or something with a read() method like a file.

Returns:

shapetuple of int

The shape of the array.

fortran_orderbool

The array data will be written out directly if it is either C-contiguous or Fortran-contiguous. Otherwise, it will be made contiguous before writing it out.

dtypedtype

The dtype of the file’s data.

max_header_sizeint, optional

Maximum allowed size of the header. Large headers may not be safe to load securely and thus require explicitly passing a larger value. See ast.literal_eval for details.

Raises:

ValueError

If the data is invalid.
