so...how do I get site packages, like Pip and P4Python installed correctly for Maya Py to see and use?  
can they just sit in the local system install and scripts directory (the default Python27 install that is) or do they have to be in the Maya python dir int eh maya install dir?

Just add extra paths to your PYTHONPATH in the Maya.env or sys.path in userSetup.py?

so Pip and P4python are already installed on my Python 27 install.. my dirs for Python27 and Python27/Scripts are already in my path.  both of course load and work fine in a standalone Python, but not in Maya..Maya does not see them..this is a more accurate question.

How do you get Maya Python to see/use modules that are installed to teh lib/site-package director of a python 27 install.

Did you update your Maya.env or your userSetup.py to include extra paths?

so I have to set the lib/site-package path then.... would be nice if there was an easier way, lol.

ok..now to figure out why standalong works fine for P4Python and why Maya Python wont load it due to some DLL error :(

I'm not sure how Maya picks up external environments on Windows. But you do have to expand its PYTHOPATH by some means to point at external locations.

As for your perforce module... compiled extensions have to be compiled to match Maya. So you may have to rebuild it against Maya's own python.

hmm...ok, discussing with our engineers...is Maya's Python 32 or 64 bit?

Should be 64-bit for any of the recent versions of Maya. What should actually matter is that it is build with the matching compiler for the particular Maya version.

Hey Justin, was this resolved? I have a similar issue with Python2.7 , P4 python  and Maya 2016.
I can import P4 just fine through a python shell, but not through Maya, I've added the path to my PYTHONPATH env variable with no luck.
It seems to import P4.py and then in line 410 "import P4API" i get the DLL load failed, cant find the specified file. Maybe it's compiled for the wrong version? but how come I can run it through shell?

Also how could I make P4Python accessible throughout the network to deploy tools like animation exporters with P4 checkout options to other 
workstations..

 I also tried something like this:
import sys
path = "C:\\Python27\\Lib\\site-packages"
if path not in sys.path:
sys.path.append(path)
import P4

and I get this:

# File "<maya console>", line 9, in <module>

# File "C:\Python27\Lib\site-packages\P4.py", line 410, in <module>

# import P4API

# ImportError: DLL load failed: The specified module could not be found. //


but I can see the "P4API.pyd" in the folder ..    :/

Thanks!

# File "\\newcastle\Tools\SDK\Maya\Tools\Python27\Lib\site-packages\P4.py", line 410, in <module>

# import P4API

# ImportError: DLL load failed: The specified module could not be found. //

I've got a build of Perforce that should work with both 2015 and 2016, its also compiled with a compatible version of openSSL if your server happens to require that.
