Please advise me on what went wrong.

Thank you.

Hi Rachel,

This problem I guess is due to the specific version of the python you use on your computer.

The multiprocessing library that comes with dexen is meant for python 2.5. 

Because the 2.5 version does not have the multiprocessing library which is needed by dexen.

However, if you try to run dexen by using python whose version is > 2.5, it will create a problem. 

First confirm the python version, you can just type in python in the command prompt. If that doesn't 

work, try to find the python installation folder. Usually the name of the folder reveals its version.

If the python version is really greater than 2.5, one suggestion is to rename the folder 'multiprocessing'

under the folder 'lib' in the root folder of dexen to something else and try running it again.

Regards,

Cihat

Hi Rachel,

Can you check that you have added the Python interpreter to your windows path. The readme file for the houdini version of dexen says:

Environment Variables
+++++++++++++++++++++

The following needs to be added to the windows PATH environment variable:

* the bin folder
  e.g. D:\dexen-32-hou-0.3.4.1\bin

* the folder containing the python interpreter - python2.5.exe
  e.g. c:\program files\side effects software\houdini 11.0.701\python25

* the houdini bin folder
  e.g. c:\program files\side effects software\houdini 11.0.701\bin

If you forgot to add the Python interpreter, then it will use the default one, which will be the wrong one.

Hi,

 

I did add python 25 into windows path. however, my houdini is "Houdini 11.0.775" instead of "houdini 11.0.701", and changing the name of the folder didnt seem to work either. Python version is 2.5.4. Is the problem with the houdini version that i have?

Can you attach a screen capture of RapidEE showing the windows PATH

I just installed the latest version of Houdini - 11.0.775
You are right - there is a problem!
I have not yet figured out what it is, but 775 will not work with shapely at the moment, and as a result, the slice_and_dice will not work.

For now, the best thing is to stick to the old version if you still have it. I will try and see which version still works, and where you can download it.

Hi Patrick,

             I have been running simulations the past week. There are 2 problems:
1. the computers do not connect to one another through dexen
2. when running simulation on single computer, everything seems fine. However, the computer will auto log off after a couple of hours and that will cause the dexen to stop running and all the simulation files will be lost.

I am running simulations on my laptop now since I can set it to never log off or auto switch off by itself.
