Flash the Beaglebone Black without SD Card

So I have been trying to install NumPy in the virtual environment without success. There have been multiple error messages, but the last was clear saying that I don’t have enough space in the BBB so my only option is to flash.
I need to flash, but I don’t have a SD Card and my faculty refuses to provide it. Is there an other way to flash the Beaglebone without a SD Card.
