Unable to run compute-rhino3d locally using local computer as server

[Grasshope (Ji)]

I was following Junichiro Horikawa’s tutorial on how to set up compute-rhino3d locally, and it was not successful.

What I did:

0. download and unzip the latest build compute-340 from this link.

1. set the following environment variables:
   COMPUTE_BACKEND_PORT = 8080
COMPUTE_HTTP_PORT = 8888
COMPUTE_HTTPs_PORT = 0

2. ran the following in PowerShell as admin:

C:\WINDOWS\system32> netsh http add urlacl url=“http://+:8080/” user=“Everyone”

URL reservation successfully added

3. and, ran the following, too:

PS C:\WINDOWS\system32> netsh http add urlacl url=“https://+:443/” user=“Everyone”

URL reservation successfully added

4. then , after I ran:
   C:\Users\USER_NAME\Downloads\compute-340>compute.frontend.exe

I got the following which seem to indicate the server is running, correct me if i’m wrong:

2020-01-21T16:19:10.1736118+08:00 dbg: frontend Logging to C:\Users\USER_NAME\AppData\Local\Temp\Compute\Logs {}

5. However, I’m unable connect to local server by running the following in a web browser:
   http://127.0.0.1:8080/version

6. and if I run the following, i got “Backend not available” shown in the web broswer:
   http://127.0.0.1:8888/version

Have I scrambled my local web server setting and system variables?

May I ask how to set up it correctly to access compute-rhino3d locally?

Thanks.

The frontend should spawn the backend process. I’d expect to see a log line like…

2020-01-24T16:20:03.7541948+00:00 inf: frontend Starting back-end geometry service on port 8080 {}

Did you configure any other environment variables, such as COMPUTE_SPAWN_GEOMETRY_SERVER?

I think I had similar problem and some how managed to make it work? Not sure though…

using the frontend~.exe files in
https://ci.appveyor.com/project/mcneel/compute-rhino3d/branch/master/artifacts

rather than from current github repo in rhino dev doc from

GitHub - mcneel/compute.rhino3d: REST geometry server based on RhinoCommon...

Also typed next code on powershell couple of times back and forth I have some how managed to get access to local server (which is actually not sure what I am doing)

netsh http add urlacl url=“http://+:8081/” user=“Everyone”
netsh http add urlacl url=“http://+:80/” user=“Everyone”
netsh http add urlacl url=“https://+:443/” user=“Everyone”

netsh http delete urlacl url=“http://+:8081/”
netsh http delete urlacl url=“http://+:80/”
netsh http delete urlacl url=“https://+:443/”

but if I try to access using http://127.0.0.1:8081/ it doesn’t work

I changed the part of the code from
https://www.youtube.com/watch?v=XCkRXAEJMhg&t=2023s
to execute it and it kind of works.
But it requires me to press enter on prompt whenever I try to run on pycharm (seems like it is requesting my approval? I barely only know how to print hello world though… )

while doing that, I was also following method from this
https://developer.rhino3d.com/guides/compute/development/

If i just try to debug from visual studio, error message shows up

Assuming there is something missing, I had to find the exe file it’s asking for - which I could not find on the github repo.

So without knowing very much anything about how to read this files, I just blindly copied the files from here
https://ci.appveyor.com/project/mcneel/compute-rhino3d/branch/master/artifacts

And now I can some how enter the debug with out that message but it actually fails in the end.

Also the example file in here

rhino-developer-samples/compute/py at 7 · mcneel/rhino-developer-samples

the line example doesn’t work.
EDIT: if I change the data tree “{0;}” to the one that matches in the ghx it’s referencing it works.
