I've just started with GAE with Eclipse under Ubuntu 12.10 and when I try to run a sample app, I've stuck with an error that I can't solve:
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
class MainPage(webapp.RequestHandler):
def get(self):
self.response.headers['Content-Type'] = 'text/plain'
self.response.out.write('Hello, webapp World!')
application = webapp.WSGIApplication([('/', MainPage)], debug=True)
def main():
run_wsgi_app(application)
if __name__ == "__main__":
main()
I got this error:
Traceback (most recent call last):

I was facing the exact same issue (but on mac) an hour or two ago. Step #5 ("Deploy It Locally") on the below instructions worked for me.
You can follow these same instructions, more or less, to get debugging to work (just do "Debug As").
http://www.mkyong.com/google-app-engine/google-app-engine-python-hello-world-example-using-eclipse/
To run it locally, right click on the helloworld.py, choose “Run As” –> “Run Configuration”, create a new “PyDev Google App Run“.
In Main tab -> Main module, manually type the directory path of “dev_appserver.py“. “Browse” button is not able to help you, type manually.
In Arguments tab -> Program arguments, put "${project_loc}/src".
Run it. By default, it will deploy to localhost:8080.
Done.

I have deployed Flask Server on IIS. I'm getting below error while importing IPython module in my code.
I have tried IPython version: 5.0, 6.0, 7.16.3 but still
When i run my code through cmd it works and server on localhost starts. But when hosted through IIS Server below issue remains If I keep import IPython line in code.
My python config:
python 3.6
Flask==1.1.2
Keras==2.1.3
scikit-learn==0.23.2
scipy==1.4.1
tensorflow==1.14.0
wfastcgi==3.0.0
Heres my code:
from flask import Flask
import IPython
app = Flask(__name__)
#app.route("/flaskapi2/")
def hello():
return "Hello from FastCGI via IIS!"
if __name__ == "__main__":
app.run()

I have a python program that uses django and it generates the error django.template.exceptions.TemplateDoesNotExist. I made a sample of code to illustrate my problem. I created two files a test_file.py and HelloTemplate.txt, located in the same directory C:\Games\Game1.
#file name: test_file.py
from django.template.loader import get_template
from django.conf import settings
settings.configure(DEBUG=True,TEMPLATE_DIRS=('.', ))
#I also tried TEMPLATE_DIRS=('C:\Games\Game1', ), didn't solve the problem
import sys
def main():
myTemplate = get_template("HelloTemplate.txt")
if __name__ == '__main__':
main()
The second file is a txt file with a line Hello as fellow:
filename: HelloTemplate.txt
Hello Template
Here's the error that I got
Traceback (most recent call last):
File "test_file.py", line 17, in <module>
main()
File "test_file.py", line 13, in main
myTemplate = get_template("HelloTemplate.txt")
File "C:\WinPython-32bit-2.7.5.3\python-2.7.5\lib\site-packages\django\template\loader.py", line 25, in get_template
raise TemplateDoesNotExist(template_name, chain=chain)
django.template.exceptions.TemplateDoesNotExist: HelloTemplate.txt
Thanks for your help to fix this error.
I guess get_template searches the file's concrete path which you define in the django project settings.py.

I had the same problem as you are facing now. In models.py file I just wrote
class Comment(db.EmbeddedDocument):
and it's content first then added
class Post(db.Document):
and then it's content. In other words, I first wrote Comment class then Post class and problem got solved ;) :) Cheers!!
Inside Post, when EmbeddedDocumentField is assigned to a variable, it needs to be pre-registered. Therefore, always register such field i.e. Comments before they are used.
I am trying to Use PyUnit within PyDev for the first time. I created a unittest.py module. When I did run as -> Python unit-test, I got the following error:
Finding files... done.
Importing test modules ... done.

My unit test is just the PyDev-generated default:
import unittest
class Test(unittest.TestCase):
def setUp(self):
pass
def tearDown(self):
pass
def testName(self):
pass
print "hello test"
if __name__ == "__main__":
#import sys;sys.argv = ['', 'Test.testName']
unittest.main()
I expected it to print hello test. What am I missing?
Ok, I realized your problem, after having a similar issue for several minutes. You need to rename your file. Name it anything other than unittest.py. This causes the compiler to confuse between your module and the unittest module that you are importing.
Second, even after you change the name of your file, you may run into the same error. That is caused by the unittest.pyc file not being removed from your project. Rename the file, delete the previously generated unittest.pyc file, and the test should run just fine.
I am currently developing wep.py application. This is my web application which is binded with web.py and wsgi.
root/main.py
import web
import sys
import imp
import os
sys.path.append(os.path.dirname(__file__))
#from module import module
from exam import exam
urls = (
'/exam', 'exam'
)
application = web.application(urls, globals(), autoreload = True).wsgifunc()
My application has an abstract class called module in module.py in root directory and its purpose is to be inherited by modules.
root/module.py
class module:
def fetchURL(self, url):
# ...
return content
The lower level module called "exam" would inherits module
root/exam/init.py
from module import module
class exam(module):
def getResults(self):
# error occurs here
self.fetchURL('math.json')
When I call the parent method, web.py raises an exception
WalkerError: ('unexpected node type', 339)
Environment: Python 2.5
How can I resolve the problem? Thanks

If it is possible I would like to turn off the template functionality as I use python only for JSON output for mobile app.
if you create python module you should add __init__.py in top of your hierarchy:
dvedit/
__init__.py
clipview.py
filters/
__init__.py
it means that in every directory which will be imported via from ... import ... should have __init__.py file.
