I've not used epydoc in the last 2 years but I found it very handy to take track of my classes and methods with a very little effort.
Today I installed latest version 3.0.1 but I get this error and searching around seems no solutions are provided.

Is epydoc project dead?
I found a patch on epydoc tracker, it was outdated anyway this part solves the problem:
markup/restructuredtext.py
307c307,310
< m = self._SUMMARY_RE.match(child.data)
---
> try:
> m = self._SUMMARY_RE.match(child.data)
> except AttributeError:
> m = None
Epydoc has not been maintained for long time and the last release is not quite compatible with current Pyton and docutils. It is still a useful tool, though, but needs some patching.
Here are some patches I used with Epydoc to build documentation for my Python 2.7 code: http://cvs.pld-linux.org/cgi-bin/cvsweb.cgi/packages/epydoc/ (they are part of the PLD-Linux Epydoc package).
I wish someone takes over the code and continue the development…
Objects can be tested against null (i.e. None) so that the exception could not be occurred.

I have a few twitterbots that I run on my raspberryPi. I have most functions wrapped in a try / except to ensure that if something errors it doesn't break the program and continues to execute.
I'm also using Python's Streaming library as my source of monitoring for the tags that I want the bot to retweet.
Here is an issue that happens that kills the program although I have the main function wrapped in a try/except:
Unhandled exception in thread started by <function startBot5 at 0x762fbed0>
Traceback (most recent call last):
File "TwitButter.py", line 151, in startBot5

File "/home/pi/twitter/bots/TwitBot.py", line 49, in __init__

File "/usr/local/lib/python3.4/dist-packages/tweepy/streaming.py", line 313, in _read_loop
line = buf.read_line().strip()
AttributeError: 'NoneType' object has no attribute 'strip'
My setup:
I have a parent class TwitButter.py, that creates an object from the TwitBot.py. These objects are the bots, and they are started on their own thread so they can run independently.
I have a function in the TwitBot that runs the startFiltering() function. It is wrapped in a try/except, but my except code is never triggered.
My guess is that the error is occurring within the Streaming library. Maybe that library is poorly coded and breaks on the line that is specified at the bottom of the traceback.
Any help would be awesome, and I wonder if others have experienced this issue?
I can provide extra details if needed.
Thanks!!!
This actually is problem in tweepy that was fixed by github #870 in 2017-04. So, should be resolved by updating your local copy to latest master.
What I did to discover that:
Did a web search to find the tweepy source repo.
Looked at streaming.py for context on the last traceback lines.
Noticed the most recent change to the file was the same problem.
I'll also note that most of the time you get a traceback from deep inside a Python library, the problem comes from the code calling it incorrectly, rather than a bug in the library. But not always. :)
When I executed in Python command
rssa = importr('Rssa')
I got eroor
Traceback (most recent call last):

Other packages are imported without problem, as example
stats = importr('stats')
tseries = importr('tseries')
forecast = importr('forecast')
I was looking for such problem, but I could not find nothing close. Please, suggest some decision of this problem.
This was caused by bug in Rssa when it tries to take control over 'decompose' function (which is exported from 'stats' package). In particular, in the list of formals '...' is added twice and this is what rpy2 is complaining about.
This will be fixed in the subsequent Rssa releases.
The only workaround is to comment out in R/common.R the following line:
formals(decompose.default) <- c(formals(decompose.default), alist(... = ))
And reinstall Rssa from source. This might be non-trivial on Windows, though R windows builder can help here.
I'm trying to get started using speech recognition in python. First I tried PySpeech (https://code.google.com/p/pyspeech/) using this code:
def listen():
while 1:
said = speech.input()
print said
if said == "off":
break
and got the following traceback:
Traceback (most recent call last):
File "C:/Users/REDACTED/Documents/Python Projects/listen.py", line 59, in <module> useful.listen()
File "C:/Users/REDACTED/Documents/Python Projects/listen.py", line 48, in listen

File "C:\Python27\lib\site-packages\speech.py", line 162, in input
listener = listenforanything(response)
File "C:\Python27\lib\site-packages\speech.py", line 193, in listenforanything
return _startlistening(None, callback)

ret = self._oleobj_.InvokeTypes(14, LCID, 1, (9, 0), ((12, 49),),GrammarId
AttributeError: 'module' object has no attribute 'VARIANT'
Then I tried dragonfly per the suggestion at the top of the GoogleCode page for PySpeech using the following example code commonly found on dragonfly docs:
from dragonfly.all import Grammar, CompoundRule
# Voice command rule combining spoken form and recognition processing.
class ExampleRule(CompoundRule):
spec = "do something computer" # Spoken form of command.
def _process_recognition(self, node, extras): # Callback when command is spoken.
print "Voice command spoken."
# Create a grammar which contains and loads the command rule.
grammar = Grammar("example grammar") # Create a grammar to contain the command rule.
grammar.add_rule(ExampleRule()) # Add the command rule to the grammar.
grammar.load() # Load the grammar.
and got this very similar traceback:
Traceback (most recent call last):
File "C:/Users/REDACTED/Documents/Python Projects/listen.py", line 14, in <module>
grammar.load() # Load the grammar.
File "C:\Python27\lib\site-packages\dragonfly\grammar\grammar_base.py", line 302, in load

ret = self._oleobj_.InvokeTypes(14, LCID, 1, (9, 0), ((12, 49),),GrammarId
AttributeError: 'module' object has no attribute 'VARIANT'
Both modules were installed using PIP and run using python 2.7 interpreter. It seems like a python version issue to me given that the same error is thrown for two different modules implementing the same thing but I'm pretty stuck on how to proceed.
Any help is greatly appreciated and I'm happy to provide more code/info as its requested. Thanks!
EDIT 1: For anyone experiencing a similar problem who happens to stumble across this post, try https://pypi.python.org/pypi/SpeechRecognition/ as an alternative on py2.7. If it runs without error but behaves inconsistently or infinite loops, try modifying the init method of the recognizer class in init.py around line 100. The energy threshold required some tinkering for me (100->300) which is likely due to the specifics of your mic setup. I also increased my quiet duration (0.5->0.7) because it would cut me off sometimes. After these changes it works fairly well for me, returning very accurate text of the input speech in ~2 seconds after capture ends.
I tried to retrieve the source code for the list class using the inspect module, without success:
>>> import inspect
>>> inspect.getsource(list)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/inspect.py", line 701, in getsource
lines, lnum = getsourcelines(object)
File "/usr/lib/python2.7/inspect.py", line 690, in getsourcelines
lines, lnum = findsource(object)
File "/usr/lib/python2.7/inspect.py", line 526, in findsource
file = getfile(object)
File "/usr/lib/python2.7/inspect.py", line 408, in getfile
raise TypeError('{!r} is a built-in class'.format(object))
TypeError: <module '__builtin__' (built-in)> is a built-in class
I don't understand why this didn't work - the documentation for inspect.getsource() says that
An IOError is raised if the source code cannot be retrieved.
... but doesn't explain why that might happen (and in any case I got a TypeError, not an IOError).
Is there some other way I can programmatically retrieve the source for an object in cases like this? If not, how can I find the source for myself?
While inspect.getsource() can retrieve the source code for objects written in Python, list is written in C, so there's no Python source for getsource() to retrieve.
If you're comfortable reading C, you can find the complete source code for Python at its official GitHub repo. For example, the source of list for various releases can be found at:
https://github.com/python/cpython/blob/master/Objects/listobject.c (latest development version)
https://github.com/python/cpython/blob/3.6/Objects/listobject.c
https://github.com/python/cpython/blob/2.7/Objects/listobject.c
... and so on.
I recently started writing a simple client using the Blogger API to do some basic posting I implemented the client in Python and used the example code verbatim from the Blogger Developer's Guide to login, get the blog id, and make a new post. I ran the script and everything went fine until I got to this line:
return blogger_service.Post(entry, '/feeds/%s/posts/default' % blog_id)
I got the error message:

By which I'm taking it that ElementTree is at fault here. I installed ElementTree via
sudo python setup.py install
in case it matters. Is there some known incompatibility between ElementTree and Python v2.7.1? Has this happened to anybody else and how did you get it working? If you need any additional information, please reply to the thread. All the source code that is relevant is basically just the example code from the Developers Guide mentioned above. I haven't modified that at all (not even the variable names). Any input is greatly appreciated.
The stacktrace is actually pretty clear about this: You're calling decode() on a list instead of a tree element. Try getting the first element from the list and calling decode() on that:
firsttext = self.text[0].decode(MEMBER_STRING_ENCODING)
