pymel.core.system.memory¶

memory(*args, **kwargs)¶

Used to query essential statistics on memory availability and usage. By default memory sizes are returned in bytes. Since Maya’s command engine only supports 32-bit signed integers, any returned value which cannot fit into 31 bits will be truncated to 2,147,483,647 and a warning message displayed. To avoid having memory sizes truncated use one of the memory size flags to return the value in larger units (e.g. megabytes) or use the asFloat flag to return the value as a float.

Flags:

Long Name / Short Name		Argument Types	Properties
asFloat / af		bool
	Causes numeric values to be returned as floats rather than ints. This can be useful if you wish to retain some of the significant digits lost when using the unit size flags.
debug / dbg		bool
freeMemory / fr		bool
	Returns size of free memory
gigaByte / gb		bool
	Return memory sizes in gigabytes (1024*1024*1024 bytes)
heapMemory / he		bool
	Returns size of memory heap
kiloByte / kb		bool
	Return memory sizes in kilobytes (1024 bytes)
megaByte / mb		bool
	Return memory sizes in megabytes (1024*1024 bytes)
pageFaults / pf		bool
	Returns number of page faults
pageReclaims / pr		bool
	Returns number of page reclaims
physicalMemory / phy		bool
	Returns size of physical memory
summary / sum		bool
	Returns a summary of memory usage. The size flags are ignored and all memory sizes are given in megabytes.
swapFree / swf		bool
	Returns size of free swap
swapLogical / swl		bool
	Returns size of logical swap
swapMax / swm		bool
	Returns maximum swap size
swapPhysical / swp		bool
	Returns size of physical swap
swapReserved / swr		bool
swapVirtual / swv		bool
	Returns size of virtual swap
swaps / sw		bool
	Returns number of swaps Flag can have multiple arguments, passed either as a tuple or a list.

# Result: 0 #

pm.memory(freeMemory=True megaByte=True)
