I am working on map automation using arcpy.
I need to add a legend on the map layout based on the layers added to the mxd.I am using the code below (as given on the tutorial):
import arcpy
mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd")
df = arcpy.mapping.ListDataFrames(mxd)[0]
lyrFile = arcpy.mapping.Layer(r"C:\Project\Data\Rivers.lyr")
arcpy.mapping.AddLayer(df, lyrFile, "TOP")
styleItem = arcpy.mapping.ListStyleItems("USER_STYLE", "Legend Items", "NewDefaultLegendStyle")[0]
legend = arcpy.mapping.ListLayoutElements(mxd, "LEGEND_ELEMENT")[0]
legend.updateItem(lyrFile, styleItem)
But everytime I run this code i get the following error:
Runtime error
Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: 'list' object has no attribute 'updateItem'
What could cause this error to appear?
What could cause this error to appear?
Well, I am not familiar with arcpy, but it seems the 0th element of whatever ListLayoutElements() returns is a list which indeed has no updateItem() method.
You might want to .append() to the list, or you might want to have a different type of object.
Your code is the same as ArcGIS Help example,
http://resources.arcgis.com/zh-cn/help/main/10.2/index.html#//00s30000006z000000
I tested the example code and it ran correctly.
By the way, I am wondering if you had pasted your own code. Otherwise you probably encounter problem in line 2,4,6 rather than the last line.
As the user2357112 suggested, you'd better try it again with clean code. Or you can confirm the type of the variable "legend" just by print type(legend)before the line
legend.updateItem(lyrFile, styleItem)

I followed this link to doc to create environment of my own.
But when i run this
from mlagents_envs.environment import UnityEnvironment
env = UnityEnvironment(file_name="v1-ball-cube-game.x86_64")
env.reset()
behavior_names = env.behavior_spec.keys()
print(behavior_names)
Game window pop up and then terminal show error saying
Traceback (most recent call last):
File "index.py", line 6, in <module>
behavior_names = env.behavior_spec.keys()
AttributeError: 'UnityEnvironment' object has no attribute 'behavior_spec'
despite the fact that this is the exact snippet as shown in the documentation.
I created environment by following this (it make without brain) and i was able to train the model by .conf file. Now i wanted to connect to python API.
You need to use stable documents and stable repo( RELEASE_TAGS ) to achieve stable results. Unity ML Agents changes it's syntax every few months so that is problem if you are following master branch.
env.get_behavior_spec(behavior_name: str)
Should solve your problem.

I'm trying to generate a random.gauss numbers but I have message error. Here is my code:
import sys,os
import numpy as np
from random import gauss
previous_value1=1018.163072765074389
previous_value2=0.004264112033664
alea_var_n=random.gauss(1,2)
alea_var_tau=random.gauss(1,2)
new_var_n= previous_value1*(1.0+alea_var_n)
new_var_tau=previous_value2*(1.0+alea_var_tau)
print 'new_var_n',new_var_n
print 'new_var_tau',new_var_tau
I got this error:
Traceback (most recent call last):
File "lolo.py", line 15, in <module>
alea_var_n=random.gauss(1,2)
AttributeError: 'builtin_function_or_method' object has no attribute 'gauss'
Someone know what's wrong, I'm a newbye with python. Or is it a numpy version problem.
For a faster option, see Benjamin Bannier's solution (which I gave a +1 to). Your present code that you posted will not work for the following reason: your import statement
from random import gauss
adds gauss to your namespace but not random. You need to do this instead:
alea_var_n = gauss(1, 2)
The error in your post, however, is not the error you should get when you run the code that you have posted above. Instead, you will get the following error:
NameError: name 'random' is not defined
Are you sure you have posted the code that generated that error? Or have you somehow included the wrong error in your post?
Justin Barber shows you an immediate solution for your problem.
Since you are using NumPy you could however use their generators as well since they appear to be significantly faster (about a factor 5-7 on my machine), e.g.
alea_var_n = np.random.normal(1, 2)
The below snippet of code keeps returning a "NoneType isn't iterable" error. Why doesn't the if statement catch this?
inset = set()
for x in node.contacted:
print type(x)
if x.is_converted() is True:
nset.add(x)
if x.contacted is None:
memotable[node.gen][node.genind] = nset
else:
nset.union(self.legacy(x, memotable))
memotable[node.gen][node.genind] = nset
Full traceback as requested:
Traceback (most recent call last):
File "F:\Dropbox\CS\a4\skeleton\trialtest.py", line 142, in

File "F:\Dropbox\CS\a4\skeleton\trialtest.py", line 125, in

File "F:\Dropbox\CS\a4\skeleton\trial.py", line 138, in legacy
nset.union(self.legacy(x, memotable))
TypeError: 'NoneType' object is not iterable
The if statement guarantees that x.contacted isn't None.
But x.contacted isn't what you're trying to iterate or index, so it isn't guarding anything.
There's no reason memotable or memotable[node.gen] can't be None even though x.contacted is something else. For that matter, we have no idea of what the code inside self.legacy(x, memotable) does—maybe it tries to iterate x, or other_table[x], or who knows what, any of which could be None.
This is why you need to look at the entire traceback, not just the error string. It will tell you exactly which statement failed, and why.
And now that you've pasted the traceback:
File "F:\Dropbox\CS\a4\skeleton\trial.py", line 138, in legacy nset.union(self.legacy(x, memotable))
Yep, it's something that happens inside that self.legacy line, and it has absolutely nothing to do with x.contacted. The problem is almost certainly that your self.legacy method is returning None, so you're doing nset.union(None).
Again, whether x.contacted is or is not None is completely irrelevant here, so your check doesn't guard you here.
If you want us to debug the problem in that function, you will have to give us the code to that function, instead of code that has nothing to do with the error. Maybe it's something silly, like doing a + b instead of return a + b at the end, or maybe it's some deep logic error, but there's really no way we can guess.
Check the value of memotable and memotable[node.gen] as it can not be said to guaranteed that they are not None if x.contacted is not None (without the code).
If you mention the values of the variables here and Post the Full Traceback, we may be able to point out the problem more precisely.
The exception occurs because the function call self.legacy(x, memotable) returns None.
The traceback indicates the error occurs in nset.union(self.legacy(x, memotable)), and set.union() raises that exception when its argument is None. (I'm assuming nset is a set. Your code defines inset = set(), but does not show where nset comes from)
>>> set().union(None)

I am getting a TypeError with a very simple script on PAMIE, and I'm not sure what I can do. I had found an answer suggesting that the library, pywin32 might not have set a self argument for this particular method (getElementsByTagName) but I don't know for sure, as I don't know where to find the definition of it.
from PAM30 import PAMIE
ie = PAMIE()
ie.navigate('google.com')
ie.getButtons()
ie.quit()
print 'done'
The error is:
Traceback (most recent call last):
File "c:\pamie1.py", line 1, in <module>
from PAM30 import PAMIE
File "C:\Python27\Lib\site-packages\PAM30.py", line 678, in getButtons

File "C:\Python27\Lib\site-packages\PAM30.py", line 939, in getElementsList
elements = self._ie.Document.getElementsByTagName(tag)
TypeError: getElementsByTagName() takes exactly 1 argument (2 given)
Here's the offending line in PAM30
elements = self._ie.Document.getElementsByTagName(tag)
where _ie_ is
self._ie = win32com.client.dynamic.Dispatch('InternetExplorer.Application')
I'm using Windows 7x64 with Python2.7 32bit
sourceforge bug link
"Workaround" seems to be enable Compatibility View (Tools > Compatibility
View settings > Display all websites in Compatibility View).
it is a bug of IE.
Work around - Change in PAMIE30
elements = self._ie.Document.getElementsByTagName(tag)
to
elements = self._ie.Document.body.all.tags(tag)
This will work without the need to use Compatibility View!
Modify this line:
elements = self._ie.Document.getElementsByTagName(tag)
to
elements = self._ie.Document.Body.getElementsByTagName(tag)
I am getting an error (see below) when trying to use cv.CreateHist in Python. I
am also noticing another alarming problem. If I spit out all of the attributes
of the cv module into a file, and then I search them, I find that a ton of
common things are missing.
For example, cv.TermCriteria() is not there; cv.ConnectedComp is not there; and
cv.CvRect is not there.
Everything about my installation, with Open CV 2.2, worked just fine. I can plot
images, make CvScalars, and call plenty of the functions, like cv.CamShift...
but there are a dozen or so of these hit-or-miss functions or data structures
that are simply missing with no explanation.
Here's my code for cv.CreateHist:
import cv
q = cv.CreateHist([1],1,cv.CV_HIST_ARRAY)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: x9y��
The weird wingding stuff is actually what it spits out at the command line, not a copy-paste error. Can anyone help figure this out? It's incredibly puzzling.
Ely
As for CvRect, see the documentation. It says such types are represented as Pythonic tuples.
As for your call to CreateHist, you may be passing the arguments in wrong order. See createhist in the docs for python opencv.
