I installed watchdog but trying to run any code doesn't work. I get that error message. Here's the code snippet. Any ideas on how to fix this?
Well, that's a very old and common issue when using Python packages. You named your file watchdog.py and the name of the package you use is watchdog too, so when you are trying to run from watchdog.observers import ... the interpreter would get confused and would try to import the current script itself.
Just rename the script to something else and everything should be all right.

I am struggling a bit to get a package to work, so I would like to just get the simplest possible test case to work.
Here is my current attempt.
Inside of a folder called Python_experiment I have two files: a jupyter notebook with the code
from .pleasejustwork import eat_muffin
and a file called pleasejustwork.py with the code
def eat_muffin():
print('i ate a muffin')
When I run the line from the jupyter notebook I get the error "attempted relative import with no known parent package". What am I missing?
The syntax you’re using is for a python package. To achieve this, place a file, __init__.py in the directory. It can be empty. If you’d like to use that package from anywhere, write a setup.py script to build and install your package. There are a lot of good tutorials on how do that, like in the python docs. Then you could do
from python_experiment.pleasejustwork import eatmuffin or from another file in the package from .pleasejustwork import eatmuffin
If you’re just trying to learn about modules, you can simply take out that leading period
from pleasejustwork import eatmuffin
I've been having troubles import pysftp. I currently have a server running some python scripts on a database, and decided to try and update this module which some of the scripts use. It broke a bunch of the scripts and then I had to go back and fix the versioning and to allow everything to function.
So far the only module I'm not able to import or use is pysftp. It throws the attached error. I've tried going into sites-manager and removing the files from there, however it has yet to help. Everything else has been working. Updating doesn't work either.
Any indication on how to resolve this error is greatly appreciated.
Error is:
ImportError: cannot import name util
I haven't been able to find a package called util to install. Please help! Attached link is of the trace.

Still learning certain things about Python... I am having issues recognizing my Python script in my scripts dir. First, I checked to see that my path is set correctly:
import sys
for pythonPath in sys.path:
print pythonPath
And C:/Users/..../Documents/maya/2014-x64/scripts is listed, which is where I am placing swap.py
In Maya's script editor I am typing the following:
import swap
reload(swap)
swap.printSomething()
I get:
Error: AttributeError: file line 3: 'module' object has no attribute 'printSomething' #
If I take the same code and throw it into a package...
C:/Users/..../Documents/maya/2014-x64/scripts/swapPackage/swap.py
And then call this, it works...
import swapPackage.swap as swap
reload(swap)
swap.printSomething()
Why? I am totally confused. Mel scripts even run fine from this location as well. I just can't get a simple python script to import and run.
Also something I noticed. Even though I can get this script to run in a package, the package name must be totally different than the module name. I can't have a package named this:
C:/Users/..../Documents/maya/2014-x64/scripts/swap/swap.py
but I can have one where the package name is different:
C:/Users/..../Documents/maya/2014-x64/scripts/swapPackage/swap.py
Ok folks, I was able to solve this by executing a print of my file, only to find out that it was sourcing a totally different version someone copied elsewhere. ARGH. This solves both issues, and makes sense why changing the package name from the module worked.
import swap
reload(swap)
print swap.__file__
It's weird to me that the import fails even when it's in the sys.path.
today, I set up a google app engine django environment on ubuntu in my lab's pc. And it works fine when I checked out the code and ran it in windows(same pc in the lab).
But when I went to the dorm, and checked out the code and start to run, it failed weirdly.
I print the sys.path, like this:
['/home/tower/googlecode/mygae', '/home/tower/googlecode/mygae/.google_appengine', '/home/tower/googlecode/mygae/.google_appengine/lib/antlr3', ...]
and when I ran python complained
from google.appengine.api import apiproxy_stub_map
ImportError: No module named appengine.api
it's easy to know the google module is in the '/home/tower/googlecode/mygae/.google_appengine'
directory, and the__init__.py for each module is present.
So what can be the reason for this weird thing? Or what I messed up probably?
thanks.
Can you import google and google.appengine?
Are you sure interpreter has read and traverse access rights to the module tree?
I had the same problem on Ubuntu when I wanted to play with google.appengine in console. First I tried to fix it by removing the /usr/lib/python2.7/dist-packages/google package altogether but Ubuntu One complained. Finally I resolved it by merging the GAE SDK google package into the package that caused the collision.
The contents of the /usr/lib/python2.7/dist-packages/google dir now look like this:
/google
/appengine
/net
/protobuf
/pyglib
/storage
/__init__.py
/__init__.pyc
Looks like you're getting a module (or package) called 'google' from elsewhere -- perhaps /home/tower/googlecode/mygae -- and THAT google module has no appengine in it. To check, print google.__file__ and if possible google.__path__; that should be informative.
Sometimes you can get an import error for a module when the error is something different, like a syntax error. Try putting
import pdb;pdb.set_trace()
just before the import and then s(tep) into the import, and n(ext) thruogh the module in question to see of you get an error.
I'm trying to use some python-2.1 code to control another program (ArcGIS). The version of python I am using is 2.5. I am getting the following error message when I run the code.
<type'exceptions.ImportError'>: No module named win32api
Failed to execute (polyline2geonetwork2).
I tried installing pywin32-214.win32-py2.5.exe but I still get the same error message. I can't figure out if I need to do anything to my original python install so it knows that I have installed this.
I think the problematic part of my code is the following:
import win32com.client, sys, string, os, re, time, math
gp = win32com.client.Dispatch("esriGeoprocessing.GpDispatch.1")
conn = win32com.client.Dispatch(r'ADODB.Connection')
Thanks for your help - I am quite new to python.
Your sys.path is
['C:\\Documents and Settings\\david\\My Documents\\GIS_References\\public\\funconn_public', 'C:\\Python25\\Lib\\idlelib', 'C:\\Program Files\\ArcGIS\\bin', 'C:\\WINDOWS\\system32\\python25.zip', 'C:\\Python25\\DLLs', 'C:\\Python25\\lib', 'C:\\Python25\\lib\\plat-win', 'C:\\Python25\\lib\\lib-tk', 'C:\\Python25', 'C:\\Python25\\lib\\site-packages', 'C:\\Python25\\lib\\site-packages\\win32', 'C:\\Python25\\lib\\site-packages\\win32\\lib', 'C:\\Python25\\lib\\site-packages\\Pythonwin']
and winapi.py is located in C:\Python25\Lib\site-packages\isapi\test\build\bdist.win32\winexe\temp.
Notice that this directory is not listed in your sys.path. To get things working, you'll need to put C:\Python25\Lib\site-packages\isapi\test\build\bdist.win32\winexe\temp in your sys.path.
It appears winapi.py is not yet installed. It is in a test\build...\temp directory.
I don't know much about Windows+Python. Maybe there is documentation that came with winapi.py which explains how the installation is suppose to be achieved.
A quick (but ugly) fix is to manually insert the needed directory into sys.path.
By this I mean, you can edit polyline2geonetwork.py and put
import sys
sys.path.append(r'C:\Python25\Lib\site-packages\isapi\test\build\bdist.win32\winexe\temp')
near the top of the file.
print out sys.path right before the import and make sure the path to win32com is in there
