NumbaDeprecationWarning: The 'nopython' keyword argument was not supplied to the 'numba.jit' decorator.

As an AI language model, I don't have the context to understand what specific code or situation this warning message refers to. However, in general, this warning message is informing the user that the Numba decorator @jit was used without specifying the nopython keyword argument. This keyword argument tells Numba to compile the function in a mode that does not rely on Python objects and thus provides better performance. Not specifying nopython=True can result in slower execution times and may not work on all platforms. Therefore, it is recommended to always specify nopython=True when using the @jit decorator in Numba.
