Signature

   def     read_array (    fp    ,    allow_pickle    =  False   ,    pickle_kwargs    =  None   ,  * ,     max_header_size    =  10000     )

Read an array from an NPY file.

fp : file_like object: If this is not a real file object, then this may take extra memory and time.
allow_pickle : bool, optional: Whether to allow writing pickled data. Default: False
pickle_kwargs : dict: Additional keyword arguments to pass to pickle.load. These are only useful when loading object arrays saved on Python 2.
max_header_size : int, 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. This option is ignored when allow_pickle is passed. In that case the file is by definition trusted and the limit is unnecessary.

: ValueError: If the data is invalid, or allow_pickle=False and the file contains an object array.
