@eirannejad Is there a way to really reset python3 in the script editor? Reason: If we change code in python vscode, we need to close rhino. After opening again it works. Whereas Tools->Reset Python 3 does not do any change. Any non standard solution would work for us too, to avoid restart of rhino.

I have the same problem with my C++ DLL in Visual Studio 2022. Once Rhino starts up and uses the DLL, I cannot recompile the DLL without restarting Rhino. Rhino puts a lock on the DLL file and will not release it without a restart. The lock prevents the build process from completing in VS as the last step of writing out the DLL is blocked. I have endured this problem for the last 4 years. So if there is some way to release the file lock in Rhino without a restart, it would be much appreciated. Regards, Terry.

C++ and .NET is I guess another thing. But for Python there is an editor that I guess could be restarted. If it is not in memory…

@Petras1 We have made improvements in Rhino 8.6 for better python reloading. You can: Use Tools → Reset Python Engine from the editor menus Use -ResetEngine option with RunPythonScript command Specify # flag: python.reloadEngine in your script to always reload the engine before running the script (both python 3 and 2)

Does it mean that we need to wait until 8.6 ? Because there is 8.5 service candidate only. And currently Tools → Reset Python Engine has no effect. I will try also the flag option. Issue is as always: development in vscode and running code in rhino.

8.6 RC is coming out next Tuesday so it’d be great if you can try that and let me know if it works

Any hope for a command to get Rhino to release its lock on the DLL file so that a new DLL can be written out by VS without restarting Rhino?

That’s Windows / dotnet runtime behaviour. Once a dll is loaded the file is locked and can not be replaced or deleted. Unless the assembly is loaded from pure binary data which causes a bunch of other problems namely Assembly.Location would return empty.

@eirannejad We tried Reset Python Engine, it does not work on the latest Rhino8 All the editable pip install do not work anymore, that previously worked before. We need to install all python packages again.

@Petras_Vestartas It would be great if you can share instructions on how to repeat this problem. There has been no major change to the python runtime layout or pip version. When rhino installs a new python environment all the existing packages under site-envs are cleared so it is important to have package references inside scripts. That ensures they are reinstalled automatically. Not sure if this is helping but I really have no idea what is your setup on your machine, what kind of libraries are you trying to reload, or what is your editable pip install package setup.

This is nice, I wish I would have known this earlier. SuperCool now this will be my way of opening Rhino
