Fork error message in Windows 10, Python 3.7

I got the following error when running reverse-geocoder. Also, the machine got really hit for a while and I could not even move the mouse.

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.
prep_data = spawn.get_preparation_data(process_obj._name)

I ran into into the same issue..If you use single threaded mode by specifying mode=1 in the search function it will,albeit slowly

rg.search(coordinates,mode=1)
