Using "open" command with python application...

On my personal computer and campus computer, the following code works (runs the python application 'buildp2p.py' :

Code (CSharp):

1. if (VariableManagerScript.Instance.calculateAxonMap)
2.             {
3.                 ProcessStartInfo processStartInfo = new ProcessStartInfo();
4.                 processStartInfo.FileName = "open";
5.                 processStartInfo.UseShellExecute = false;
6.                 processStartInfo.RedirectStandardOutput = false;
7.                 processStartInfo.WindowStyle = ProcessWindowStyle.Maximized;
8.                 processStartInfo.CreateNoWindow = false;
9.                
10.                 string pulse2perceptCmdCall = "python " + pythonPath+"build-p2p.py " +
11.                                   pythonPath
12.                                   + " " + BackendShaderHandler.Instance.simulation_xMin + " " + BackendShaderHandler.Instance.simulation_xMax + " " + BackendShaderHandler.Instance.simulation_yMin + " " +
13.                                   BackendShaderHandler.Instance.simulation_yMax + " " + BackendShaderHandler.Instance.simulation_xyStep + " " + VariableManagerScript.Instance.rho + " " + VariableManagerScript.Instance.lambda +
14.                                   " " + VariableManagerScript.Instance.axonContributionThreshold + " " + VariableManagerScript.Instance.number_axons + " " + VariableManagerScript.Instance.number_axon_segments + " " + VariableManagerScript.Instance.useLeftEye;
15.                 UnityEngine.Debug.Log(pulse2perceptCmdCall);
16.                 processStartInfo.Arguments = pulse2perceptCmdCall;
17.                
18.                 Process process = Process.Start(processStartInfo);
19.                 process.WaitForExit();
20.                 UnityEngine.Debug.Log("Done waiting");
21.                
22.             }

Debug of the call prints this:


On someone else's windows 10 machine, an error pops up when calling that exact command with a different path for their machine (ie. "python C:/Users/chtun/OneDrive/Documents/UCSB_RMP_BionicVisionLabProject/UCSB_RMP_Bionic_Vision_Lab_Project/Assets\BionicVisionVR\Coding\python\build-p2p.py C:/Users/chtun/OneDrive/Documents/UCSB_RMP_BionicVisionLabProject/UCSB_RMP_Bionic_Vision_Lab_Project/Assets\BionicVisionVR\Coding\python\ -17.14706 17.14706 -17.14706 17.14706 0.6470588 100 50 0.0001 300 300 False"):

The weird part is, the command works if he copy/pastes into a command prompt (including storing the result files in the Unity Assets folder).

Any idea why Unity is failing to call python properly on his machines?

 

open

is a MacOSX shell shortcut to launch a MacOSX process.

On Windows the closest equivalent is

start

but they are not fully interchangeable.

If the above is from Windows, maybe you have an

open

replacement?

 

Thank you for the reply. I think we got it figured out... After he restarted his computer it ended up working. I believe there was something cached somewhere with the project path and initially he had spaces. He replaced them with underscores but it was still calling the old path, even when he had completely closed and restarted Unity.
