Orca.exe hangs on write_image, freezes up and I have to kill the process


#1

When I run the following code it hangs indefinitely.

Plotly.io.write_image(fig, self.save_path + ‘/’ + self.save_name + ‘_Scree.jpg’)

If I wrap the write_image with a Try, it will not move off the code below to show me any errors.

plotly.io.orca.config.executable = ‘C:\inetpub\wwwroot\MProd360\Python\orca\orca.exe’
Note: orca.exe is launched fine.

All other code before the write_Image executes fine.

Background: I am calling the python code from an asp.net application.
I have run the write_image code from two other personal web servers without hanging.
I moved the code to a server hosted on a Go Daddy dedicated server and I then get the hanging behavior.

Also, If I run the code purely within a Python project in Visual Studio on the Go Daddy server it runs without hangings as well.

public string run_Python(string sCMD, string sAgs1, string sArgs2)
{
string result = “”;

    ProcessStartInfo start = new ProcessStartInfo();
    start.FileName = "C:\\Program Files\\Python37\\python.exe";
    start.Arguments = sCMD + " " + sAgs1 + " " + sArgs2;
    start.UseShellExecute = false;// Do not use OS sarg2
    start.CreateNoWindow = true; // We don't need new window
    start.RedirectStandardOutput = true;// Any output, generated by application will be redirected back
    start.RedirectStandardError = true; // Any error in standard output will be redirected back (for example exceptions)
    using (Process process = Process.Start(start))
    {
        using (StreamReader reader = process.StandardOutput)
        {
            string stderr = process.StandardError.ReadToEnd(); // Here are the exceptions from our Python script
            if (stderr != "")
            {
                result = stderr;
            }
            else
            {
                result = reader.ReadToEnd(); // Here is the result of StdOut(for example: print "test")
            }
            Debug.WriteLine("*****************************************************");
            Debug.WriteLine("*****************************************************");
            Debug.WriteLine(result);
            Debug.WriteLine("*****************************************************");
            Debug.WriteLine("*****************************************************");


            return result;
        }
    }
}
