I am new to ROS and python. This question could be silly but spent almost 5 hours on this. I am using PyCharm (Latest version) with Python 2.7.15 64 bit (Also tried with 3.x). I need to import a few libraries as below:
import roslib;
roslib.load_manifest('smach_tutorials')
import rospy
import smach
import smach_ros
However, PyCharm fails to identify roslib, rospy, smach and smach_ros (could not find in the interpreter also to import). The above libraries are example given in the official site:
http://wiki.ros.org/smach/Tutorials/Simple%20State%20Machine
OS: Windows 7 (64 bit)
ROS not installed: ("SMACH is a ROS-independent Python library to build hierarchical state machines" - from the official site)
Error Traceback:
Traceback (most recent call last):
File "C:/Users/****/Desktop/Python/TestCharm.py", line 3, in <module>
import roslib;
ModuleNotFoundError: No module named 'roslib'
If you are using the catkin version of ROS (Groovy and later), it does not use the manifest file but uses the package.xml file instead.
So your code will be:
import rospy
import smach
Apparently, your code is ready for ROS Fuerte or earlier version.
With supposing that Smach is ROS-independent, you need only to the import smach
Thanks for all the support. I found out it is not possible for my perticular case to use SMACH because it has dependency on catkin. I am using Windows 7 and should be upgraded to windows 10 or use Ununtu Linux.

I need to test unity 3d app on mobile device (or emulator). I do not want to press on buttons using coordinates only, so I want to use Sikuli. I will describe steps that I have already done:
Downloaded and installed Sikuli v1.1.1
Installed java 32bit
Installed jython 2.7.0
jython added as interpreter in my project in pyCharm
sikulixapi is run
Copied Sikuli lib from appData to jython folder
Created Python file and added imports
And when I try to run project I receive this error:
D:\jython2.7.0\bin\jython.exe -Dpython.path=D:\python_projects\sikuli_test D:/python_projects/sikuli_test/test_sikuli.py
Tra**ceback (most recent call last):
File "D:/python_projects/sikuli_test/test_sikuli.py", line 1, in <module>
from sikuli import Region
File "D:\jython2.7.0\Lib\sikuli\__init__.py", line 5, in <module>
from org.sikuli.basics import Debug
ImportError: No module named sikuli
Process finished with exit code -1**
What am I doing wrong?
The following works for me:
import org.sikuli.script.SikulixForJython
before
from sikuli import *
In your jython project interpreter, set the environment variables path to where your sikuli jar is placed. That should fix it.
Also make sure to use this in your code
import org.sikuli.script.SikulixForJython
from sikuli import *
I am trying to run this python rewrite of Vlfeat library.
https://github.com/shackenberg/phow_caltech101.py. I am trying to run the application phow_caltech101.
This is throwing
File "/A/B/C/pyvlfeat-0.1.1a3/vlfeat/__init__.py", line 1, in <module>
import _vlfeat
ImportError: No module named _vlfeat
In the corresponding "init.py" file, I can see it is mentioned as "import _vlfeat". I am new to python, please let me know what is causing this error?
You need to download and install PyVlfeat module.
https://pypi.python.org/pypi/pyvlfeat/
As I see, pyvlfeat has some dependencies, so be sure to download these too:
Boost.Python (tested against version 1.35.0-5)
NumPy (tested against version 1.5.1)
Matplotlib (tested against version 0.99.3)
Im trying to compile Godot engine following the instructions here
When I run scons bin/godot as the tutorial says, I get the following error:
scons: Reading SConscript files ...
ImportError: cannot import name _args_from_interpreter_flags:
File "/home/grayfox/github/godot2/godot/SConstruct", line 9:
import multiprocessing
File "/usr/lib64/python2.7/multiprocessing/__init__.py", line 65:
from multiprocessing.util import SUBDEBUG, SUBWARNING
File "/usr/lib64/python2.7/multiprocessing/util.py", line 40:
from subprocess import _args_from_interpreter_flags
The SConstruct file starts this way:
EnsureSConsVersion(0,14);
import string
import os
import os.path
import glob
import sys
import methods
import multiprocessing
...
If I try to run python SConstruct I get an error complaining about missing functions defined by scons (i.e. the script fails after doing all the imports).
Commenting import multiprocessing fixes the issue but I don't want to modify that file, as I would have to revert the change if I ever make a pull request. The project is quite active so I believe this has something to do with my local configuration.
Any ideas why the script is failing to import _args_from_interpreter_flags only if I execute it via scons?
[UPDATE]
I did a fresh Gentoo install and the problem persists. I did some tests and I found this:
In a python terminal>
>>> import SCons.Script
>>> from subprocess import _args_from_interpreter_flags
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name _args_from_interpreter_flags
>>> import subprocess
>>> subprocess.__file__
'/usr/lib64/python2.7/site-packages/SCons/compat/_scons_subprocess.pyc'
But the output is different if I do this:
>>> import subprocess
>>> subprocess.__file__
'/usr/lib64/python2.7/subprocess.pyc'
So I update my question: Is this a bug? Can anybody reproduce it in other distros? If it's a bug, should I report it to Gentoo or to SCons?
[ANOTHER UPDATE]
Adding temp.extend([os.path.join(x, 'lib64') for x in prefs]) did't work, same error.
Adding print sys.path at the beginning of the compact module gives:
['/usr/lib64/python-exec/python2.7/scons-local-2.3.0',
'/usr/lib64/python-exec/python2.7/scons-local',

It looks as if this isn't really a problem connected to SCons directly. You might have an alien "subprocess" module/package installed in your system. Also check out Cannot import name _args_from_interpreter_flags which seems to be related.
Based on your updated question: I tried to compile Godot on my machine (Python 2.7.3, SCons 2.3.1, Ubuntu 12.04 LTS) and it's running fine, so the problem is not related to the provided SConstruct (and its supporting build description files in subfolders). The "_scons_subprocess" module gets used only when the import of the original "subprocess.py" fails. So I suspect that the SCons start script sets up a wrong sys.path, which may happen under 64bit (see issue http://scons.tigris.org/issues/show_bug.cgi?id=2657 ).
After you added "temp.extend([os.path.join(x, 'lib64') for x in prefs])", your "print sys.path" statement shows paths like "/usr/lib64/python-exec" in its output. A Google search turned up the page http://forums.gentoo.org/viewtopic-t-985402-start-0.html for me. It describes an issue with Gentoo, where programs are installed as links to pip. Please follow the given advice and see if this fixes your problem.
It's a bug in Gentoo's scons-2.3.0 and scons-2.3.1 ebuilds (see bug report). It has been fixed in versions 2.3.1-r1 and higher.
I am running Eclipse (Indigo) with PyDev, Python 2.6 and PyWin32 (build 217, 32 bit), and having a problem that gets stranger the more I investigate.
I'm running a Python program that imports the following 3 libraries:
import win32con
import win32file
import pywintypes
win32con imports properly but win32file does not (note: win32con is a pyc and win32file is a pyd, in raw Python):
Traceback (most recent call last):
File "....\dynamic\testpywin32.py", line 2, in <module>
import win32file
ImportError: DLL load failed: The specified module could not be found.
I tried the equivalent in pure Python 2.6 (IDLE) and everything imported properly.
Comparing sys.path in IDLE and Eclipse, the only thing not in Eclipse is ['C:\Python26\Lib\idlelib']; the only extra thing Eclipse has (besides the workspace) is C:\eclipse\plugins\org.python.pydev.debug_2.2.4.2011121401\pysrc.
In addition, I went on and used the following commands right after startup, through the debugger:
sys.path = [sys.path from IDLE]
os.environ['PATH'] = [os.environ['PATH'] from IDLE]
which didn't seem to help.
What's going on here?
which windows version are you using??
i am using windows XP + pydev plugin and its works.
go to python path and try to fix the python eggs path, and press apply
i have installed pyjamas on debian
http://pyjs.org/getting_started.html
however my program does not find the module, what could be the problem, i have installed pyjamas correctly using apt-get
krisdigitx-virtual-machine ~ # python jamas.py
Traceback (most recent call last):
File "jamas.py", line 3, in <module>
from pyjamas import Window
ImportError: No module named pyjamas

from pyjs import Window
from pyjs.ui import RootPanel, Button
from pyjs.ui import HTML
def greet(sender):
Window.alert("Hello Krishna!")
b = Button("click me", greet)
Rootpanel().add(b)
After some research:
i had to do pyjsbuild jamas.py to get the output directory, however it gives me a new error
jamas TypeError: jamas.RootPanel().add is not a function
Since you get an
ImportError: No module named pyjamas
you may need to add the module's path to $PYTHONPATH with
export PYTHONPATH=$PYTHONPATH:/usr/share/pyjamas/library
Please go to http://pyjs.org/GettingHelp.html
The first link "Getting Started" is a detailled walkthrough for an installation to start from scratch. Basically, what it says there is: Get the up-to-date source code from the git repository.
All steps to get Pyjs and Pyjs Desktop running are described in the Wiki article in the necessary detail, but still concise enough.
