-upgrade pip and setuptools:
open command prompt: press windows key or “start” and type “cmd” and then enter:

UPDATE the registry for performance:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters:

DWORD:
	MaxUserPort
	Set a large value such as 65534 (0x0000fffe). See MS KB 196271.

	TCPTimedWaitDelay
	Set the minimum value (0x0000001e). See MS KB 149532.

	StrictTimeWaitSeqCheck
	Set to 1 so TCPTimedWaitDelay is checked.
