Error: _vhstack_dispatcher() takes 1 positional argument but 9 were given

[deanhystad]

Please post error message and trace.

The documentation for vstack says it takes one tuple.

https://numpy.org/doc/stable/reference/g...stack.html

You are providing 9 arguments.

Let's count.

        (ptb / y[4] * y[5] / np.sqrt(y[5]**2 + y[6]**2) * function_deo(y[4], y[5], y[6], y[9], ptb, mqb, pes) - 1 / y[2]**2 + y[1]**2 / y[2],
         ptb / y[4] * y[6] / np.sqrt(y[5]**2 + y[6]**2) * function_deo(y[4], y[5], y[6], y[9], ptb, mqb, pes) - y[0] * y[1] / y[2]),  #1
                
        y[0],  #2

        y[1] / y[2],  #3
        
        -mqb * function_deo(y[4], y[5], y[6], y[9], ptb, mqb, pes),  #4
        
        y[6] * y[1] / y[2] - y[7],  #5
        
        -y[5] * 2.0 * y[1] / y[2] + y[6] * y[0] / y[2] - y[8] * 1.0 / y[2],  #6

        y[5] * (-2.0 / y[2]**3 + y[1]**2 / y[2]**2) + y[6] * (-y[0] * y[1]) / y[2] + y[8] * y[1] / y[2]**2,  #7
        
        0,  #8
        
        ptb / y[4]**2 * (np.sqrt(y[5]**2 + y[6]**2)) * function_deo(y[4], y[5], y[6], y[9], ptb, mqb, pes)  #9
        )

I count 9.

Number 1 is a doozy. Unlike the others, it is a tuple all by iteself, and it does this twice:

ptb / y[4] * y[5] / np.sqrt(y[5]**2 + y[6]**2) * function_deo(y[4], y[5], y[6], y[9], ptb, mqb, pes)
