PyCallGraphException: The command "dot -Tpng -oML4AR2 pycallgraph.png C:\Users\XXXX\AppData\Local\Temp\tmpxw3sbjz1" failed with error code 1.

I have repeatedly tried PyCallGraphException with different results. I have gotten it to work with max_depth=4, but not max_depth=5. I do not appear to have a file named "tmpxw3sbjz1" (or similar file with a recent timestamp). Dot is in my path and I can execute the command manually from within Jupyter, but this command ("dot -Tpng -oML4AR2 pycallgraph.png C:\Users\XXXX\AppData\Local\Temp\tmpxw3sbjz1" ) does not work.

Here is the code

    from pycallgraph import PyCallGraph
    from pycallgraph import Config
    from pycallgraph import GlobbingFilter
    from pycallgraph.output import GraphvizOutput

    pycall_exclude = ['time.*', 'datetime.*', 'dateutil.*', 'argparse.*',
                    'numpy.*', 'pandas.*', 'yaml.*', 'pickle.*',
                    'psutil.*', 'sys.*', 'warnings.*', 'sklearn.*', 
                    'collections.*', 'scipy.*', 'tqdm.*', 'os.*',
                    'logging.*', 'pycallgraph.*']

    config = Config(max_depth=5)

    config.trace_filter = GlobbingFilter(exclude=pycall_exclude)
    graphviz = GraphvizOutput(output_file='ML4AR2 pycallgraph.png')

    if __name__ == '__main__':
        with PyCallGraph(output=graphviz, config=config):
               main()
