Forecasting issue

[mspringfield1]

I'm trying to use this file in my own enviroment. I've set up the enviroment, installed the requirements.txt and have opened it up in jupyter notebook just as the README suggests but when I run the code, its holding up just after the forward model process. The line that it's crashing at is

(wsat.past.Prior, prod.past.Prior) = forward_model(nTime, wsat.init.Prior, perm.Prior)

The error message I'm receiving is

A Jupyter widget could not be displayed because the widget state could not be found. This could happen if the kernel storing the widget is no longer available, or if the widget state was not saved in the notebook. You may be able to create the widget by running the appropriate cells.

RemoteTraceback Traceback (most recent call last) RemoteTraceback: """ Traceback (most recent call last): File "C:*\Anaconda3\lib\site-packages\multiprocess\pool.py", line 125, in worker result = (True, func(args, kwds)) File "C:*\Anaconda3\lib\site-packages\pathos\helpers\mp_helper.py", line 15, in func = lambda args: f(args) File "C:\\AppData\Local\Temp\ipykernel_4264\2723154157.py", line 10, in run1 NameError: name 'copy' is not defined """

The above exception was the direct cause of the following exception:

I;ve also ran the MAIN python file in VS Code and ran the debugger and it's resulting in an error in the utils.py file on line 157.

return p_map(fun, list(args), desc=desc, num_cpus=nCores, leave=leave)

Exception has occurred: RuntimeError (note: full exception trace is shown but execution is paused at: )

    An attempt has been made to start a new process before the
    current process has finished its bootstrapping phase.

    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.

I'm not sure why this result is happening because I followed all the steps to run the code on my own server. Any help would be great.

I'm guessing this is a Windows/Python/MPL/Multiprocessing issue. Cannot debug it in detail at the moment, but you can probably get around it by replacing the line

mp = get_map(multiprocessing=4)

mp = get_map(multiprocessing=False)

or with

mp = map

Yes, it's a windows issue. The code you gave (mp = get_map(multiprocessing=False)) ending up working to have the code run without interruption. I'm now trying to figure out why some of the plots wont show when I run the code. When I launch jupyter notebook it defaults to microsoft edge which may be the problem but I'm not sure.
