The problem was due to ffmpeg turning the pdg graph to dynamic. Turning the PDG server end “dynamic partition” option solved the problem.

It looks like a but. I can make It to work in some situation. I´ve sent a RFE.

Found some info online about problems with firewall that could trigger this error. But I´ve got the same error with the firewall turned off (I´m on Windows 10 here).

Hi guys,

I´m getting some errors while trying to create a “Version” entity on Shotgun with TOPs.

I´m using the same setup as the help files: I find the current project using the shotgun find (one) and It returns the current and correct project. I´m de admin, so I have all permissions and I can create a version using the same “method” by using the python shell. Only on TOPs I get following error:

Traceback (most recent call last):

I figured it out. When the HDA Processor creates the parameters, It overrides the attributes. Must disable the HDA´s parameters on the processor for it to work.

BrandonA
Yes, this is possible. You can use an attribute to drive the HDA Path, and then create attributes that match the parameters on the HDA, and they will be automatically applied to the corresponding HDA parameter when the work item cooks.

thanks for the reply! That´s what I thought, but I didn´t manage to get it to work. Do you have a working example?
I even tried the hdap_attribute, but It didn´t work….

Hi,

Does anyone know if we can control HDA´s parameters in the HDA Processor using TOPs attributes without hardcoding them in the parameters tab?
To clarify: my idea is to find HDAs in a folder, put them in attributes and then use the attribute “HDA path” to tell the HDA Processor which HDA to process (that´s working fine).
The next step is to fine-tune the HDA´s behavior with TOP´s attributes - but I can´t hardcode them in the parameter´s tab because I´m not using the same asset to process.

Hi,

I´m chaging my workflow to make use of HDA Processors, but I can´t figure out why it can´t output geometry (it outputs empty bgeos)., even when testing with the example files.
The asset is a simple HDA with a platonic inside, so no inputs are needed.
I´ve saved the debug hip file, and the hda comes in locked (as if it was missing the asset), but It´s not, as can be seeing in the image attached (04).
I´ve tried the example files but got the same result and didn´t find anyone else having this same kind of error.


SOLVED - There is something in my pipeline scripts that is messing up with houdini.

Any tips on solving the “Error: Executable “python.exe” is not rooted, and does not exist in the current directory or in the PATH” problem?
I´m getting the same on one of my machines.

chrisgreb
Maybe worth trying with the most recent daily build? Can you run other TOP nodes ok? Otherwise if you like you could submit a hip file with a bug ticket and we could continue from there.

Thanks Chris. Everything else works as expected, just this node that is not working as (I think) It should.

I´ve submitted a ticket for this. Thanks for the help.

Hi @chrisgreb,

Any thoughts about why it works everywhere, but not in the Shotgun Session TOP node?

sorry about that.
It worked.

the file “._pdg_shotgun_info_test” has this contents:

and the log file “test_shotgunrpc” is empty.

Got a different error message.
The “error” in the beginning is from my pipeline scripts, but I already tested with default user preferences and got the same errors.

pprint(result)

Hi Chris,

It works in the Houdini´s python shell. It works on hython too (with the command line tools).
I think it´s something in the pre-cook pass.

chrisgreb
Are there any log files in the temp folders? They may contain error messages.
Otherwise, could you please attach a hip file here or to a support bug for us to try to reproduce.

Hi Chris,

There is no file in the temp folder (although it creates the folder, but not the files).
I just used a simples file with a TOPnet with a Shotgun Session inside, nothing fancy.

The strange thing is: the example file in the docs worked at some point last week, but not anymore. And both computers had a Windows update going on after that, so I´m assuming is something related to that, could it be?

Are there some tests I could perform to try to narrow down the problem?

chrisgreb
It times out if the shotgun ‘server’ doesn't write to a specific temp file after a few seconds. The server is just a hython process. Could it be failing to write to your temp directory? You could take a look in the pdgtemp/log folder in houdini_temp or working directory to see if anything is written there.

Hi Chris, thanks for the reply.
No, Hython doesn´t save the file in the temp folder. I used a custom folder and the default folder. None of them worked.

The first of several to come. Next planned ones are:

API

- A deep dive on the PDG API.

Please let us what further questions / topics we could address beyond those above.

Ken, I watched your masterclass (thanks, BTW), but I think there still room to talk more about mappers and where to use them. I still don´t understand why the attributes are lost when there is a mapper in the middle…

Yeahh, will be nice to know more about the API and why there are some differences from hou, like, why something like self.evalParm must be different in PDG.

Hi,

I keep getting this error when I try to connect to my shotgun site using the PDG Shotgun Session node.
The strange thing is that I did connect a few days ago, but now I can´t. Same problem on both machines, build 293, but same thing with 321. Perhaps is a windows update problem?
I can import the SG api in the command line tools with hython and in the python shell inside houdini, and connect to my shotgun site. Only with PDG I can´t.

Yes, inside houdini´s python shell I can. I´ve shotgun running and SG python tab open inside houdini. But I still get error´s saying that Houdini can´t find SG API. As I posted, I pointed out the “PYTHONPATH” environment to the “shotgun_api3” folder. Is that correct? Do I need to add extra folders to the environment?

Got it. Was a problem with the pythonpath. Thanks for the help, and I hope someone can help you too!
