I am using the VS code interactive window and using some python packages that make use of other programs. In the interactive window I am e.g. getting error messages like:
OSError: No command "mcflirt" found on host login2.nan.kcl.ac.uk. Please check that the corresponding package is installed.
If I was just running this from the command line I would simply ensure that I loaded the package which contains 'mcflirt' into the shell before starting the python interpreter and the interpreter would then be able to find it. Is anyone aware of how to tell the interactive window to load the package (e.g. loading the mcflirt containing package by module load fsl)before starting the python interpreter?
One way to access system modules is to use the python 'init' file e.g.:
sys.path.insert(0,'/software/system/modules/4.5.1/init')
import python as mod
mod.module('unload', 'fsl')
mod.module('load', 'fsl/6.0.4')
mod.module('load', 'ants/2.3.5')

I would like to use python scripts in Jmeter, so I can check the Load and the performance of an application...for that I've created a Thread with JSR223 Sampler, and I put the content of python script, and after the run, Jmeter throws error like : File "", line 8, in
ImportError: No module named opcua, ModuleNotFoundError: No module named 'dateutil'
see snapshot:
I don't know how to install this modules (package)in Jmeter, with PyCharm, I installed the package in the Project Interpreter under the setting see the snapshot...
You can do something like:
Install required module(s)
jython -m pip install foo
Add the next line(s) to the beginning of your script:
import sys
sys.path.append('\\location\\of\\jython\\site-packages')
However from performance perspective it will be much better to re-write your script in Groovy as calling Jython interpreter is not the best choice when it comes to high loads.
Also be aware that you can invoke Python interpreter as "external" process using JMeter's OS Process Sampler (if amount of the existing Python code is too big or too complex to rewrite in Groovy), see How to Run External Commands and Programs Locally and Remotely from JMeter for more details.
I'm new to using atom and was wondering how to run a python script on it. I have code written at the moment which works perfectly fine in normal python shell, using tkinter, however when I run it through the command line, it says:
import tkinter as tk
ImportError: No module named tkinter
How do I fix this? In my environment variables I have already added python.exe, the file directory to the actual script I'm running and to the python download itself. How do I fix this?
The best way is to load the Jupyter plugin. It's called Hydrogen. Then under the packages menu, you can select Hydrogen/Run all and it will run your python code. there is a keyboard shortcut for doing this which speeds up the process. You can easily check your code as you write it by using the hydrogen option to run a line and go to next line.
As for your Tkinter problem have you loaded Tkinter? You can do this using pip install Tkinter. After that try running your code again.
In python 2.7 and below, the modules's name is Tkinter, while in 3.0 and above, it is tkinter.
Atom (whatever this is) seems to use a 2.7 or below version of python interpreter.
Folks,
Just getting started using OGR and Python for a variety of geospatial tasks. I'm working outside of OSGEO4w, and have installed GDAL w/ Python Bindings as well as Python v. 2.7.8 on my machine.
That said, I can run python and import gdal from a command-line interface but am unable to import the module when I use the IDLE environment. It returns an error telling me that the module doesn't exist. My install must be sound given that it works in the cmd prompt, so what's the deal?
This is all new to me, I'd appreciate any help or advice ya'll can impart; all previous questions I've read were concerned w/ merely installing (which I've done successfully) and getting Python to recognize the module from the command prompt, which it does.
Cheers,
Mike
Mike,
You can open IDLE with your python installation from the cmd line through:
>>>from idlelib import PyShell
>>>PyShell.main()
This should open IDLE from your current python, and you should be able then to import gdal and ogr from there.
Alternatively, you should have a windows batch file here
C:\YOURPYTHONPATH\Lib\idlelib\idle.bat
Running this should achieve the same.
Martin
Consider creating the following batch where PyInst references the Python installation folder from which IDLE is launched (i.e. idle.bat) and QgisInst references the folder containing "bin\o4w_env.bat":
#echo off
set PyInst=C:\Python27
set QgisInst="C:\Program Files\QGIS Brighton"
call %QgisInst%\bin\o4w_env.bat
set PYTHONPATH=%PyInst%\DLLs;%PyInst%\Lib;%PyInst%\Lib\lib-tk
set TCL_LIBRARY=%PyInst%\tcl\tcl8.5
python %PyInst%\Lib\idlelib\idle.pyw
I am using Python 3.3 (2.7 is also installed) and a compatible version of pygame. Recently I have been trying to switch from IDLE to Notepad++
I am using a saved shortcut in Notepad++
C:\Python33\python.bat "$(CURRENT_DIRECTORY)" "$(FILE_NAME)"
which runs the batch file:
#echo off
cd %1
%2
if not errorlevel 1 goto quit
echo.
echo.
pause
:quit
When I run C:\Python33\Foldername\imp_prob.py
import pygame
in IDLE it works fine, in Notepad++ using that shortcut it gives an ImportError: No module named pygame
My questions are:
Why is the NP++ method not producing the same result?
How can I change the shortcut or batch file to make it run stuff that IDLE can run?
What method can I use to ensure that I can import a module regardless of which directory I am running the program from?
edit: a working alternative was in the answers to How do you run a python script from within notepad++?
I had some issues with the code they provided, but replacing "python" with the full path to my python33 install solved that.
I still don't understand why pygame wouldn't import when using my run shortcut. I also don't understand why NppExec works when Run doesn't.
It sounds like you would need to set your systemvariables. Idle does not require these steps. You entered the full path to the python.exe in np++ to execute the python program, but the path to the modules etc. is still unknown.
Add the paths, and try again.
System Properties -> Advanced -> Environment Variables, in the bottom window look for a "Path" variable, Edit and append the following the existing entries (do not delete anything in there!)
;C:\Python33;C:\Python33\DLLs;C:\Python33\Lib
for Python 3.3, if you have installed it into its default directory.
To see if everything worked, open the console anywhere (shift+rightclick -> Open Command Window Here) and just type "python". The python console should open, telling you that you use python 3.3. You then also do not need to tell np++ the full python path, but instead can just use "python" again.
although I have been using python a long time very easily in a Linux environment, I have tremendous trouble to even install it correctly in a windows environment. I hope this is a question to be asked here, as it is not directly a programming question.
Especially, I have the following problems:
When on the command line, python is not a recognized command. Do I have to set the Windows path manually myself? If so, how to do that?
When starting a python script, should this be done with python.exe or pythonw.exe? What is the difference?
I also tried to install ipython several times, it never got installed (even after following the starting ipythonenter link description here thread.
When starting a script with python.exe, a window pops up and closes immediately. I saw some hints in putting in a readline command, which is of no help if there is a syntax error in the script. So how to be able to keep the window open, or how to run the command on the cmd.exe?
Thank you for any help on these items.
Alex
1) Look here: www.computerhope.com/issues/ch000549.htm
2) It has already been answered, always try to use search before asking question:
pythonw.exe or python.exe?
4) When using cmd.exe just navigate to your script folder using dir for changing directories and C:,D:,etc. for changing drives. Then run script by typing just the script name. When installed correctly, Python automatically launches .py scripts with python, so you don't have to write 'python' before script name. When run in cmd, window will stay open. If you want it to stay open even when launching script with double-click, use function waiting for user input, see here How to keep a Python script output window open?
You might want to use Python3.3, there is a new launcher for Python scripts in it. By that, you can start Python scripts with py <scriptname> which has the benefit of being installed in your path (C:\Windows\system32) and you can use a shebang to tell whether the script is for Python2 or Python3.
Also
In addition to the launcher, the Windows installer now includes an
option to add the newly installed Python to the system PATH
(contributed by Brian Curtin in issue 3561).
