Error 00075 Input Features Value is Required

PeteVitt

Hi - I've got a python script that takes four points and makes a shapefile. I've put the script inside a model and want it to provide the input to a Minimum Bounding Geometry Tool. I've created a derived output parameter in the script that provides the input, but I get the subject error when I run the model -- the part of my code where I try to generate the output parameter is:

ptFile = gp.CreateFeatureClass_management(outFolder, outFile, "Point", "#", "#", "#", sr)
.....
arcpy.SetParameterasText(0, ptFile)

the script runs fine on its own, and creates a shapefile, but somehow this output parameter is not getting passed to the Minimum Bounding Geometry Tool

Attached is a screen shot of my model
Any ideas about what I'm doing wrong?

Thanks

Thank you for your help - it is working now when run as script and in the model

Several issues here:
- You're mixing gp = arcgisscripting.create() with arcpy. Choose one or the other. While it's technically feasible to mix them in a script, there are numerous issues that can arise.
- A tool returns a result object. You were setting the output parameter to this result object and it fails.

Here's a snippet (from your code) that works with arcpy... Note that I'm using SetParameterAsText. I tested this in a model and it updates the derived output correctly

arcpy.env.overwriteOutput = True


#sr = gp.CreateSpatialReference("C:\\Program Files\\ArcGIS\\Desktop10.0\\Coordinate Systems\\Geographic Coordinate Systems\\North America\\NAD 1983.prj")
sr = "#"
result = arcpy.CreateFeatureclass_management(r"E:\scratch\scratch.gdb", "Test", "Point", "#", "#", "#", sr)
ptfile = result.getOutput(0)
arcpy.AddMessage("output feature class is: " + ptfile)
arcpy.SetParameterAsText(8, ptfile)
arcpy.AddMessage("Checking: set output parameter 8")

uploaded wrong script on previous post -- this is it

Here's a blog post on getting error descriptions. It may help you to debug.

Can you share your model/script tool?

PeteVitt

the error is definately occuring at:
arcpy.SetParameterAsText(8, ptFile)
as I've added a Message below this line and the script jumps to the exception -- is there any way to get a description of the error exception? Its very odd because the shapefile gets created successfully

Thanks

Pete

You may be setting the wrong parameter with SetParameterAsText. You have 8 input parameters. Your derived output should ALWAYS be the last parameter. Therefor, you should be doing SetParameterAsText(8, ptFile). Also make sure that ptFile has a valid value (i.e., add a message to check its value).

Try running your script tool with all the input values once and save the model.
Now connect the output of the script tool to the next tool.
Make sure that the feature type that your script tool is creating is an accepted as a valid input type for the next tool.
Remove all the previously added input values from your script tool parameters to make the tool a generic tool once again.
