[GIS] import arcpy failed Python 2.7 with ArcGIS 10.3 64-bit Background geoprocessing RuntimeError: NotInitialized

#memory#error64bitarcpybackground-geoprocessingpython-2.7

I want to run a python script that uses arcpy. It was running earlier on a 32-bit machine without problems. On a 64-bit machine I get a MemoryError. The 64-bit backgroundgeoprocessing of ArcGIS 10.3 should solve this problem. If I type import arcpy to the IDLE which is 64-bit too I get the following error message:

Traceback (most recent call last):
  File "<pyshell#20>", line 1, in <module>

    envset = (set(env for env in self._gp.listEnvironments()))
RuntimeError: NotInitialized

To make sure I installed everything correctly:
ArcGIS 10.3 (Advanced Concurrent License);
ArcGIS 10.3 64-bit backgroundgeoproessing patch;
Python 2.7.9 x64

I also adapted the system paths fron …\bin to \bin64 and from Python27\ArcGIS10.3 to \ArcGISx6410.3

10.3 does not use 2.7.9. For this reason I can tell you've installed your own Python. If you install your own, you need to have made sure you've installed numpy, matplotlib and a couple more packages that escape me right now.

Quite honestly, the easiest way to "fix" this is to go back and start from scratch.

uninstall BG
uninstall Python 2.7.9
remove the entries you've created in the path that point to Python
just install BG64. Thats it. no pointing of paths, no worrying about getting the right packages. The installer will make sure everything gets laid down in the correct spot.

Right now you're going to play whack-a-mole trying to find what piece you have that is pointing at something incorrectly.

If you absolutely do want to play the game of trying to fix it...its probably an issue with your paths. Instead of adding to your system path, BG uses a .PTH file, generally located here when you have a default install: "C:\Python27\ArcGISx6410.3\Lib\site-packages\DTBGGP64.pth"

Inside the file will be 3 lines:

C:\Program Files (x86)\ArcGIS\Desktop10.3\bin64
C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy
C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcToolBox\Scripts

If you replicate this workflow with the file and these paths in your site-packages directory, it may lead you in the right direction.

[GIS] Avoiding import arcpy error (RuntimeError: NotInitialized) when using IDLE

Looking at your posts here and on the ESRI Forums, I think you have some muddled environment settings.

You want to put C:\Python26\ArcGIS10.0 in your system PATH variable, that gets you to the correct executables from IDLE, PythonWin or the command line.

Your PYTHONPATH could be empty. Or, you could just include the 3 stanzas of your Desktop10.pth file: C:\Program Files (x86)\ArcGIS\Desktop10.0\bin C:\Program Files; (x86)\ArcGIS\Desktop10.0\arcpy; C:\Program Files (x86)\ArcGIS\Desktop10.0\ArcToolbox\Scripts--those paths will then take precedence over the the default search for modules (below the python.exe or pythonw.exe being called).

Finally, since you've uninstalled and installed several versions of Python. At this point, there should be nothing under the C:\Python26 folder except the ArcGIS10.0 folder of the ESRI provided Python 2.6.5 32-bit install. If there is a Lib file there it is a residual of an earlier install and will interfere. It would be a bigger problem if any or your prior Python26 installs were 64-bit.

Also, since you're on 64-bit Windows 7, the Registry path the to 32-bit Python keys are HKLM\SOFTWARE\Wow6432Node\Python If you have a HKLM\SOFTWARE\Python, they would be Keys for a 64-bit install. They also would interfere with the 32-bit install.

[GIS] Export attributes of shapefiles into text file

As I mentioned in the comments, ListFields on an invalid data source is the probable cause. There are several other issues that are going to trip you up once you solve that though. I took a rough pass at the code

import arcpy
import csv

table = r'your_input'
output = r'your_output'

fields = arcpy.ListFields(table)
field_names = [field.name for field in fields if field.type != 'Geometry'] 

with open(output, 'w') as f:
    w = csv.writer(f) 
    w.writerow(field_names)            
    for row in arcpy.SearchCursor(table):  
        field_vals = [row.getValue(field) for field in field_names]  
        w.writerow(field_vals)
    del row

If you're using at least 10.1, you'd be better off using arcpy.da.SearchCursor.

import arcpy
import csv

table = r'your_input'
output = r'your_output'

fields = arcpy.ListFields(table)
field_names = [field.name for field in fields if field.type != 'Geometry'] 

with open(output, 'w') as f:
    w = csv.writer(f) 
    w.writerow(field_names)            
    with arcpy.da.SearchCursor(table, field_names) as cursor:  
        for row in cursor:
            w.writerow(row)
