I downloaded the most recent daily build of H18, as of this writing 18.0.338, and opened the python shell.
It says:

How do I enable python 3 in Houdini 18?

Thanks

you need to download Hourini18 Python3 Tech Preview version

on Daily Builds Download page either scroll a bit down or click on Houdini Python 3 filter button

Ok, I'll give that a try. Thanks!

I downloaded houdini-py3-18.0.338-macosx_x86_64_clang10.0_10.14.dmg
and installed it.
But when I open the python terminal, I still get 2.7.x, not 3.x.
What am I missing?

Hello,

I downloaded today's 18.0.340 Python 3 Tech Preview build for Mac and it definitely is built against Python 3. Not only did the Python Shell report “Python 3.7.4” but the Houdini main window frame also said “Python 3” at the top.

I recommend a re-install since it looks like you have a Python 2 build of Houdini installed. So uninstall Houdini, unmount any existing Houdini images from your system (this can be done in Finder), then open the houdini-py3*.dmg file and run through the installation as usual.

Cheers,
Rob

Ok, I'll try again with the newer 18.0.340 Python 3 Tech Preview build.
Strange that python 3 didn't work with houdini-py3-18.0.338-macosx_x86_64_clang10.0_10.14.
Thanks

Tomas, will you advise to use a Houdini python 3 package over the old 2? Is is stable enough?
Could i install python 3 over my already install h18 python 2.7?


Thanks

I download and install the daily python 3 tech preview by the launcher, installed is completed but inside there is still no python3 folder, only 2.7… I need it for Scipy and so

Is it a bug?
Note that i have also other houdini version installed and i do not want not to get rid of then .

Is it a bug? How could i manage to get it properly installed with python 3, i looked for options but can t see one on this point…
I off course download the right houdini install manager….

Is it not possible to just download the full package straight?

Cheers

I just installed houdini-py3-18.5.442-macosx_x86_64_clang10.0_10.14.dmg then opened the Python shell in Houdini and it reads
