Hi Chris, I haven't tried using edit.stopEditing(False), but I did try simply commenting out edit.stopEditing(True), which removes the error.  I'm assuming that "edit" was never really a valid Python edit object because the editor arcobject (at the heart of the Python editor object) is a singleton object, so only one instance can exist at a time.  An "edit" session can't be closed if it doesn't really exist, hense the error.  No clue why the start/stopOperations don't cause errors. Unfortunately the add-in framework requires edit sessions to be started within the add-in for SDE edits, so I have to put in the edit.startEditing(True,True) code just to avoid the errors, but the "editor" within the addin otherwise unfunctional.  I'm pretty sure that my add-ins worked with all of the edit code included, as long as the user did not have a pre-existing edit session running in ArcMap, but that doesn't seem to be the case now (10.3 upgrade, maybe?), so now I don't have much of a reason to keep the edit.stopEditing(True) line in my add-ins.  However, I just discovered another post by someone else who just removes that line, and they noticed some issues if they try to make additional edits on newly created features that haven't been properly saved. Bottom line, I think, is that there is no "correct" way to handle this arcpy/SDE edit issue... just different workarounds with different disadvantages. Kerry ... View more

Chris, Thanks for the manual edit workaround.  You're right...it isn't convenient to remember to have to do manual edits, and it's hard to explain to others who might use the scripts. I added arcpy.da.edit code to my scripts that edit SDE data, even if the scripts might be executed from within ArcMap during an edit session.  The "edit.startOperation()" function prevents "The requested operation is invalid on a closed state" error from being thrown.  It's an ugly workaround, but I had to use it with a similar issue within my Python Add-ins to bypass an apparent hardwired "protection" against making edits to SDE data without being in an edit session. However...there are some weird consequences of starting the edit session within the script when it already exists in ArcMap.  Although there is a "fatal" error in the script when it encounters edit.stopEditing(True), the edits actually persist.  The edits made by the script can also be "undone" if there was a manual edit before the script was run, but the previous manual edit will also be undone.  I remain somewhat concerned about the potential issues due to improper handling of the edit session and edit operations with SDE data, but it might be less of an issue for us than others, since we register our data as "versioned moving edits to base" and rarely have to deal conflicting edits.

If you are ok with using an older version of pandas, the installation process I used was relatively simple: I installed pandas by running an executable installation file (built with distutils) downloaded from pypi.python.org via download links on the pandas homepage​.  The key for me was choosing an older version of pandas that was built using the same version of NumPy that I was already running. To find out what version of numpy you are running, import NumPy and then type: numpy.version.full_version Although pandas 15.2 is the latest release, it (the executable installation file) requires NumPy 1.8.1.  I'm running ArcMap 10.2 which comes with NumPy 1.7.1.  I browsed through the older releases of pandas (listed on the right hand pandas homepage) until I found a release that was based on NumPy 1.7.1, which happened to be pandas 12.0​.  It was only later that I realized that the pandas 13.0 and 13.1 were also based on NumPy 1.7.1, but I didn't bother to change it. Although python-dateutil and pytz are listed as pandas 15.2 dependencies, I think they aren't for pandas 12.0 since I didn't bother installing them. I hope that helps! Kerry ... View more

I had already deleted all the .pyc and .pyo files from comtypes/gen.  At your suggestion I also deleted them from the comtypes folder, but I still had errors (I forget which).  I uninstalled and reinstalled comtypes-0.6.2 (from sourceforge) and that seems to have fixed everything!  Sometimes a fresh start is easier than figuring out what went wrong. ...

Alas, I do not have Background Processing enabled.  Any other ideas? ... View more

I'm running from the ArcMap Python window.

Our methods of searching for keys have the same functionality, and they're both described here. ... View more

Since Ian brought it up, I'll add that you don't need specify the full path for the output feature class either, as long as you want it to be saved in the already-specified workspace. As with most geoprocessing tools, CopyFeatures_management honors selections and definition queries, so make sure you know what you're copying. If the code below doesn't work, try commenting out the try and except lines (and de-indenting the arcpy.CopyFeatures_management and print lines) to see what error occurs. Also, I found typos in my previous post.  There should only be one line (that looks like this) in the except block:      print 'Could not copy %s'%layer.name import os  import arcpy   arcpy.env.workspace = ws = 'C:\\WorkSpace\\sahie_saipe\\sahie_saipe.gdb'  dictionary_Layer = {'co06_Layer':'co06', 'co07_Layer':'co07', 'cnty08_Layer':'co08', 'co09_Layer':'co09', 'co10_Layer':'co10', 'co11_Layer':'co11', 'co12_Layer':'co12', 'st_Select':'state'} mxd = arcpy.mapping.MapDocument('C:\\WorkSpace\\sahie_saipe\\sahie_saipe.mxd') for layer in arcpy.mapping.ListLayers(mxd):      if layer.name in dictionary_Layer.keys():         try:            arcpy.CopyFeatures_management(layer.name, dictionary_Layer[layer.name]) #only 2 required parameters, full path not necessary to output to workspace           print 'copy %s to %s' %(layer.name, dictionary_Layer[layer.name])         except:            print 'Could not copy %s'%layer.name ...

Hello, The variable "layer" represents the layer object, not the name of the layer (a string).  You therefore need to look for layer.name in the dictionary, and more specifically look in the list of the dictionary keys.  I've copied your code and edited lines 6-12 below for clarification... hopefully I didn't introduce typos!
