PlasmaCalcs.tools.arrays.memory_size_check_loading_arrays_like(array1, nload=1, *, MBmax=UNSET, dtype_min=UNSET)

raise MemorySizeError if loading nload arrays like array1 will be too large.

Too large if total size in MB would be more than MBmax.

array1: array, e.g. numpy array

must have .nbytes attribute, which tells size in bytes.

n: int

number of arrays like array1 which will be loaded.

MBmax: UNSET, None, or int

maximum size allowed, in Megabytes.

UNSET –> use DEFAULTS.ARRAY_MBYTES_MAX

None –> no limit.

dtype_min: UNSET or numpy dtype

calculate memory as if array elements will have at least as many bytes as dtype_min.itemsize.

(if array elements already have more bytes than this, use array.dtype instead.)

UNSET –> use DEFAULTS.ARRAY_MEMORY_CHECK_DTYPE_MIN

None –> don’t impose any minimum, just use array.dtype.

return size of array1, in MB.
