Error in calling a Python application (+ OpenCv) in Visual Studio 17 (C #)

I'm trying to make a "control panel" that each button will call a Python application (+ OpenCV) but when I run it through the PyCharm IDE, or straight from the folder, it runs perfectly, but when I make the call through Visual 17 , it appears the following error [ link ]

visual call (c #)

private void button1_Click(object sender, EventArgs e) { System.Diagnostics.Process.Start("C:/Users/Barce/PycharmProjects/OpenCV/exemplo3.py"); }
