pythonOCC examples doesn't work?

[Jayden]

I installed
(1) pythonxy2.7.2.3 (with python2.7) and
(2) pythonOCC-0.5-all-in-one.win32.py26
on windows 7 64 bit computer.

I try run pythonOCC examples in its example folder, such as the helloworld.py and got errors as follows:

ImportantError: DLL load failed: The specified module could not be found.

The error come from the line of code:

from OCC.BrepPrimAPI import *

How to fix the error? Thanks a lot!!

Hi Jayden,

It has been some time ago that I used PythonOCC and I used it on Linux, so I cannot be of much help here. It sounds like you have to tell Windows where to look for the installed libraries (environment variables?). Anyhow, I recommend to post the question to the PythonOCC mailinglist. They are quite responsive.

One last suggestion. OCC itself comes with a small utility called DRAWEXE. It is a tcl/tk program that can be used to play around with a lot of the functionality provided by OCC.

Good luck!

Can you safely mix these?

See above, I hope, I don't actually know

So used to google, forgot to check the python docs:

http://docs.python.org/faq/windows.html

and this should be useful as well, which is from:

http://stackoverflow.com/questions/5030362/how-to-use-opencv-in-python

"I suspect you have the same problem I've run into. If you have a 64-bit
version of Python, it cannot load 32-bit DLLs. OpenCV currently only ships
32-bit binaries. If you want 64-bit .pyd and .dll files, you have to
compile them yourself. There are some
instructions<http://opencv.willowgarage.com/wiki/VisualC++>on the
OpenCV Wiki, but it's not for the faint of heart. Expect to have a
substantial time investment.

The easiest solution is to:

1. Uninstall 64-bit Python
2. Install a 32-bit distribution.

The PythonXY distribution includes pyopencv -- a good set of OpenCV hooks.
The only limitation is that it's 32-bit, so don't make plans to process
gigapixel astronomy data with it!

If you *must* have the 64-bit version, follow these
instructions<http://redkiing.wordpress.com/2010/10/03/opencv-and-visual-studio-2010-with-cmake/>to
get it OpenCV to compile with Visual Studio 2010. There's a discussion
on stackoverflow that describes building 64-bit apps with VC Express."


And again, check on the pywin mailing list

All very impressive, but as Dennis Lee Bieber has pointed out and which
I suspected there is a binary incompatibility between the OP's Python
version and pythonOCC version. Others would be able to see this for
themselves but you insist on sending email without context. Please
don't do this.

 

[Dwight Hutto]

All very impressive, but as Dennis Lee Bieber has pointed out and which I
suspected there is a binary incompatibility between the OP's Python version
and pythonOCC version.

DIdn't see this, I was too busy helping the OP search for an answer,
and educate us both at the same time.

Others would be able to see this for themselves but

you insist on sending email without context. Please don't do this.

How are my emails without context? I'm referring the OP to the docs,
as well as posts related to their question. It goes to use google, and
RTFM, and putting it politely to them.

I could summarize, but they have to do the real reading. I'm not
researching this, and if I was, I'd charge for the time. This is to
show that things can get complex if you don't use google, or read the
docs.

Why does the OP keep asking here, when there are answers out there.
especially on the pywin list, which Windows users are usually referred
to.

Please point out what's out of context. The links and references place
it into context if the OP finds them useful, and I believe I searched
well for them.

Would the OP like to tell me I wasn't helpful? Because now they're
probably on a search to figure out how to make these compatible, which
means more questions, and more reading.

Plus the OP said he's on 64. Read the quote from stackoverflow:


"I suspect you have the same problem I've run into. If you have a 64-bit
version of Python, it cannot load 32-bit DLLs. OpenCV currently only ships
32-bit binaries. If you want 64-bit .pyd and .dll files, you have to
compile them yourself. "

A different program, but roughly the same in analogy, I do believe.

And where in here was the OP referenced to the python docs on windows:

Was that out of context as well?

Let's not argue about this, I was pointing them to what I saw as the
best possible resources to overcome his current problem, and it was
all in context of the conversation as far as I'm concerned.

 

[jelle]

You installed python 2.7 and expect a 2.6 module to work with it.
That won't work. Finally, you need to install the OpenCasCade libs to be able to run PythonOCC.

I think that is the reason. Thanks a lot!!

 

[Terry Reedy]

No need to do this, at least not on windows.

in a separate directory. I have had both on my win7 machine so I could
run (test) python code on both. One can put python-code-dir.pth in the
site-packages directories of both.

Context is not the same as explaining absolutely everything.
It means that I, the reader, can see *what* youare talking about

I do agree with the stance not to spoon feed OP(s).

I was not aware that Windows users were "usually" referred anywhere.
Most referrals are on a case-by-case basis as many problems or
questions from Windows Python developers are Python questions and
not specific to pywin.

Your point is taken. Most of the time, if it's in an in line response
I would write the email line by line, with the referenced text shown
above my response.

However, when it seems like a conversation, I just trim the above, and
respond. That's how I view an e-mail, like an ongoing conversation.

From now on, I'll leave the mailing I'm responding to above, and

delete the point's I'm not talking about, which is about what I
usually do.

So being attacked about no context(which was an attack out of context,
based on a few messages one night), when the whole conversation is in
the topic reader/gmail/etc seemed a little ignorant to reading
through. All he had to do was look back up to the email s just above
my response, and see, or read just through mine, not read everyone.

But anyway, I'll be more informative as to exactly what I was
referencing, instead of treating it like an ongoing conversation where
everyone was present, and paying attention to the whole of the topic.

If it were a private email -- you to the OP -- that would be
reasonable; they should know what they'd asked.

However... This is a cross-linked Usenet <> mailing list, and Usenet
does not guarantee that all posts will arrive in logical order... It is
possible that once could see your response BEFORE the OP's post has
propagated to the same Usenet server.

And if you look at the above in gmail, you can see the ...'s that when
not clicked, won't show some of the responses I leave just above, and

That's a Gmail feature, and a sop to people who can't take a moment to
trim quoted text. Taking your above post as an example, there were
(according to my calculation) 111 lines of text that had already been
sent, being _re_sent in your post.

Not everyone uses Gmail. And not everyone runs off 100Mbit internet
connections. And even if everyone were to use Gmail off 100Mbit
internet connections, I would still recommend trimming the text,
because Gmail gives you precisely two options: all the way collapsed,
or all the way expanded. If I want to read more context, I get _all_
the context. That's still not all that useful.

Right while you make a post is the best time to decide how much
context is needed. Spend just a few seconds thinking about how much to
trim, and you can make things easier for everyone who reads your post,
whether it be on python-list, comp.lang.python, or one of several
web-accessible archives. And remember, this is for posterity, so be
honest. How do you feel? Interesting...

[Dwight Hutto]

honest. How do you feel? Interesting...Um, I guess like an inconsiderate bandwidth hog, but from now on I'll
trim more text.

First it was too little, and now it's too much.

I just tend to cut out some or all depending on the scope of the conversation.

If I just hit reply all, and send it out, it's not intentionally to
use all of the text, and utilize the extra space, it's just a
response.

If the conversation is kind of just a few people, then I trim pretty
much everything, which apparently set a guy name mark off, who I was
polite to, but I'm not going to get slammed for a few simple posting
mistakes, and more than likely a few of his aliases, or the group he
tends to cheer up with.

It's just a mailing list, lighten up because mistakes in posting will
happen, even by accident.

What you may have missed was that that was a quote from Princess

response.

It's all a question of courtesy, and there's no hard-and-fast rules.
But as a simple rule of thumb, assume that your post is going to be
read completely without any surrounding context; will it be
comprehensible?

If the conversation is kind of just a few people, then I trim pretty
much everything, which apparently set a guy name mark off, who I was
polite to, but I'm not going to get slammed for a few simple posting
mistakes, and more than likely a few of his aliases, or the group he

There's actually no such thing as a conversation of just a few people,
on a big list like this. Sure, there may be only a few contributors,
but there are thousands - maybe millions - of readers.

You're not being slammed, though. What you're seeing is a community
doing its best to maintain itself. If we all sit silently, wishing our
hardest that everyone would quote nicely, cite nicely, post without
trolling, and be helpful, will it happen? (Those familiar with the
Bible may note a similarity with some comments in the epistle of
James.) There are two ways to ensure that the community upholds its
standards: Kicking out everyone who doesn't measure up, or explaining
to people and inviting them to participate. The first is a great way
to have a tiny community with no growth. The second... is what you're
seeing.

Of course, there's a third option, which is to simply ignore
everything and try to get on with life. That basically amounts to
kicking _yourself_ out of the community, because you'll quickly give
up on a forum in which everyone posts sloppily. And I'm sure you don't
want all the experts to do that, because you're then left with a
"blind leading the blind" mailing list... not particularly conducive
to good code!

It's just a mailing list, lighten up because mistakes in posting will
happen, even by accident.

Accidents are understandable, but getting defensive doesn't help
Generally, people don't speak up until there've been several similar
instances.

No, only the individual can killfile, then they miss the point of

propaganda, and not an actual cause(to join a group).
