There are many instances when you are running one of the tools with multivalue inputs (merge, append, union) and you may not have the same number of input datasets each time. If you simply connect your (lets say 3) input datasets to merge but leave one of the inputs blank then merge won't run. You can get around this by connecting your inputs to the collect values tool and then passing those values on to merge. However, in order for this to work your downstream intermediate outputs need to be left blank. This means that each time you run your model in ModelBuilder that you would need to go in and set or unset the intermediate outputs. Ugh!! Furthermore, this precludes running your model as a tool. Double Ugh!! I propose that Esri re-design the collect values tool to honor empty values. This could even be implemented as an optional check box. This would allow for more flexible models.

Hi all, I was wondering if there has been any progress on this issue or if anyone has heard whether Esri has plans to address this. From what I can gather these lock issue seem to be affecting nearly everyone who does editing or ModelBuilder in 10.x, and Esri hasn't made any plans to address this?????? This seems like a big enough and significant issue that pretty much affects every Esri user that should be addressed immediately. Has anyone come across another post or forum that has a potential solution? -Tom

Thanks Stuart, This helps a lot, and your explanation is very clear. I'm in the process of re-installing right now and will set the PATH and PYTHONHOME variables. I had installed the Enthought for python and had forgotten that I had it on my computer. Prior to uninstalling I had tried just changing the the PATH and PYTHONHOME variables, but that alone didn't end up doing the trick. If I'm understanding what you're saying correctly if I want to run 64bit python for scripts outside of ArcGIS I should simply be able to change the PATH and PYTHONHOME variables temporarily to point them to the 64 bit version? -Tom

Stuart, where didn't work but the others did (see attachment). A while back I had installed the 64-bit python 2.7 for another program that ran on python, and I guess I was thinking that the ArcGIS uninstall would have gotten rid of it and installed the 32-bit version over it. Maybe the best solution would be to wipe python off my computer and re-install from scratch?? -Tom

Hi Stuart, Thanks for your quick response. I can't seem to get your commands to work. I'm going to the command prompt, typing in "python" to get it to python, and then typing in "where python" I get the following error: File "<stdin>", line 1 where python SyntaxError: invalid syntax -Tom

Hi, I'm able to run scripts as tools in ArcToolbox but I can't seem to run them from IDLE directly since upgrading to 10.1. Initially I had SP1 for background geoprocessing but have since rolled that back thinking that it might help. The same problem occurs. I get the following error in IDLE: Python 2.7.3 |EPD 7.3-2 (64-bit)| (default, Apr 12 2012, 15:20:16) [MSC v.1500 64 bit (AMD64)] on win32 Type "copyright", "credits" or "license()" for more information. >>> ================================ RESTART ================================ >>> Traceback (most recent call last): File "X:\for_tdilts\outbox\GIS_tools_scripts\ClimaticWaterDeficit\Version10_1\extras\DurCWD_normal.py", line 6, in <module> import arcpy File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\__init__.py", line 21, in <module> from arcpy.geoprocessing import gp File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\geoprocessing\__init__.py", line 14, in <module> from _base import * File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\geoprocessing\_base.py", line 14, in <module> import arcgisscripting ImportError: DLL load failed: %1 is not a valid Win32 application. >>> Is it that ArcGIS somehow is managing to point to 64 bit python but IDLE needs to be directed there? Is there some sort of document with instructions that I need to be following for "post-install" of ArcGIS Desktop??? -Tom

I'm getting a traceback error when running OLS. According to http://downloads.esri.com/support/downloads/other_/189810.1_SP1_Announcement.pdf this was noted as a bug - NIM080983 - OLS (Ordinary Least Squares) returns a traceback when some of the data written to the coefficient table is NaN (not a number). Does anybody know if this has been addressed or will be addressed? I've got 10.1 SP1 and in the issues addressed document it doesn't list this bug fix anywhere http://downloads.esri.com/support/downloads/other_/ArcGIS101sp1-issues.htm . -Tom Dilts
