<p>Don, please try your tests in a python virtual environment.
Thanks!</p>
<p>I'm up-to-date, I'm almost positively sure. I just converted the
X3D archives (about 1-2 hours ago) to python using
X3dToPython.xslt, and there were many, problems with Protos. I
can rerun with logging enabled, if you want to look at the logs.
(but you don't seem inclined, so I'll only do it on request). I
ran inside X3DJSONLD, and got a ton of problems with Protos. I
have 66 files with Protos out of 160 X3D files. So it's not some
random fluke! 51 of the python files had the issue.</p>
<p>You can look through your logs by searching for isinstance:</p>
<p>``` if not ProtoBody is None and not
isinstance(ProtoBody,(ProtoBody,ProtoInstance)):<br>
TypeError: isinstance() arg 2 must be a type or tuple of types</p>
<p>```</p>
<p>Those lines basically tells it all. The ProtoBody parameter is
being used as a type, AFAICT<br>
</p>
<p>Here's a few you may have in the 3D archives:</p>
<p>Figure31_9SpinGroupPrototype.x3d</p>
<p>AllenDuttonProtoInstances.x3d<br>
AllenStandShootRifleM24.x3d</p>
<p>HelloWorldProgramOutput.x3d</p>
<p>What I have discovered, is, I have to enable a virtual
environment in python to get the errors for these python program.
Otherwise, I get other errors. These files haven't been modified
since Aug 16, but X3dToPython.xslt changed on Jun 10. I don't
know why enabling the virtual environment make a difference.<br>
</p>
<p>This is the script I ran, pretty much. I saw many Exceptions
thrown around ProtoBody, ProtoDeclare:</p>
<p>=========================================================================<br>
</p>
<p>!/bin/bash<br>
<br>
# Run the Test Suite<br>
<br>
# accepts files with .x3d extension<br>
export PROCESSORS=${PROCESSORS-8}<br>
<br>
. ./classpath<br>
<br>
echo translating to python<br>
(find /c/x3d-code/www.web3d.org/x3d/content/examples -type f -name
'*.x3d' | grep -v intermediate | grep -v "\.new") | xargs -P
$PROCESSORS java net.coderextreme.RunSaxon ---overwrite ---silent
--../lib/stylesheets/X3dToPython.xslt -py
---../python/net/x3djsonld/data/<br>
echo running python<br>
pushd ../python/net/x3djsonld/data<br>
export PYTHONPATH=`pwd`<br>
find c -name '*.py' | xargs -L 1 -P $PROCESSORS python3<br>
popd</p>
<p>=====================================================================================</p>
<p>I saw no other types of errors in my sampling. Perhaps you could
point out a python example, or send me an example that works with
Protos, and I could test it on my system?</p>
<p>I actually have 3 different rubik's examples. So it would take
some investigating and remembering if I sent the same one again.
I'm fairly sure I chose the simplest one I have. abox.x3d and
x3domflowers.x3d are others. Still the overwhelming report is
from the archive, but perhaps I need a Savage update? Nope.<br>
</p>
<p>Here to help the blind walk and the lame see! In the 5th
dimension of course!<br>

<p class="MsoNormal">John, we have a lot of simple prototypes

have all tested OK.<o:p></o:p></p>

<p class="MsoNormal">If your example is that Rubiks’s cube with
nested prototypes, that is harder. We believe the spec is OK
but that feature is only occasionally demonstrated as
working. Any model with nested prototypes (ProtoDeclare
within ProtoDeclare) can be easily refactored by putting all
of the ProtoDeclare blocks first. Similarly it makes sense to
test individual ProtoInstance nodes without feeding them
nested ProtoInstance fields.<o:p></o:p></p>

it may be a wider problem with x3d.py, because when I
patched Protos in my version, there were further issues.
So simply patching Protos won’t fix all the issues.
