jupyter notebook MemoryErrory

When I used jupyter for the first time on a new notebook today, a MemoryError occurred. I checked the notebook memory, a total of 8G, and less than 4G was used, so it should not be the memory limit of the notebook itself. 32-bit python is installed on the notebook, which may be causing this problem. So I uninstalled python32-bit again (to uninstall, just re-run the installer and select uninstall), installed 64-bit python, and the problem is solved.
