Hi everyone, hopefully Sidefx team, i got several issue and a contant crash of a file i would like your suggestion how to deal with this problem.

- Download get-pip.py from (save as a file) and place it in your Houdini python37 folder (e.g. C:\Program Files\Side Effects Software\Houdini 18.0.456\python37).
- Run windows cmd with admin rights and navigate to your python folder (e.g. cd “C:\Program Files\Side Effects Software\Houdini 18.0.456\python37”).
- Execute the command “python3.7.exe get-pip.py” and wait for pip to finish installing. pip.exe should now appear in the /Scripts folder.
- Execute the command “python3.7.exe -m pip install scipy” and wait for Scipy to install.

All good. But when launching Houdini i got this first error log:

An error occurred while validating an asset's license:
Traceback (most recent call last):
File “<stdin>”, line 37, in set_up_pycrypto_imports
File “C:\PROGRA~1\SIDEEF~1\Houdini 18.0.566\python37\lib\site-packages\Crypto\Signature\PKCS1_PSS.py”, line 74, in <module>
from Crypto.Util.strxor import strxor
ImportError: DLL load failed: Le module spécifié est introuvable.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File “<stdin>”, line 1, in <module>
File “<stdin>”, line 54, in main
File “<stdin>”, line 19, in __enter__
File “<stdin>”, line 40, in set_up_pycrypto_imports
NameError: name ‘reload’ is not defined


Then many weird behavior. Then my setup keeps crashing. I attached the file

Is it a bug on your side, does someone has an idea?

Cheers

Again my Dear
Like I posted everywhere ..
Have You copied Otls and Hda to env Houdini.
that link that you got From me on FaceBook or Odforce cant remember When..
http://page.math.tu-berlin.de/~chern/projects/Clebsch/ [page.math.tu-berlin.de]
Like you see it works On Mine Vers. maybe its crashing for some reason that you have some parallel issues with OTL..respective Hda..try to install this version ..

Did You install Right Version With Houdini Python 3-last menu
Houdini 18.0 - Python 3 Tech Preview

My dear Tesan, i know , i have been using computer since 15, im 44 now and have usually no worry, it s odd…

Yes, maybe there are some conflic with other HDA and OTL i have installed as i have also a h18 python 2 version.
I will give a try. Im following this method after, with success to install the additional library… Hmmmm

Hope Sidefx will make it part of the default installation in the next version

Hum tried everything and noway, Houdini crashes one second after trying to cook the OTL solver, i have none other hda installed, clean install, weird

Even Houdini by itself, You can't even middle click on some node like volume_vop , volumevisualization to display the info, very unrealiable … At least on my side without having any special configuration

Can't even move the network box in the nodal panel, the viewport frequently refuses to refresh or at some point canùt simply rename nodes… There is something really weird going on here, would love to get more feedback what could be the issue; because i tried many build, uninstalled anaconda / miniconda, check my system env path, tried everything i could kind of imagine

Blender use python 3, have no issue at all…

Cheers, sorry to repost …
