ArcGIS 10.2, five WofE layers. |
|
Ok, please create empty text file called DEBUG into toolbox\arcsdm\ directory and rerun the project for more detailed output. It could be some error in parameters or perhaps incompatibility with 10.2. |
|
I modified the following codes: Traceback Error Info: Traceback (most recent call last): Failed to execute (LogisticRegressionTool). |
|
And, I have tried to short the file name (tmp_UCras0, e.g. UCr), but the erros still exists. |
|
I have referenced the ArcGIS help, but I don't think my new codes have any problem. Combine_sample.py Set local variablesoutRaster = "C:/data/final_1" Check out Spatial Analyst extension licensegp.CheckOutExtension("Spatial") Process: Combine...gp.Combine_sa("'C:/data/ras_1';'C:/data/ras_2'", outRaster) If an error occurred while running a tool, then print the messages.print gp.GetMessages() |
|
What is the output of this (print it after it is set): |
|
Input_Combine_rasters ="r'F:\data_processed\ltemp\bwof_gch1_G1'; r'F:\data_processed\ltemp\bwof_ghy1_G1'; r'F:\data_processed\ltemp\bwof_int1_G1'; r'F:\data_processed\ltemp\bwof_sta1_G1'; r'F:\data_processed\ltemp\bwof_str1_G1'" gp.Combine_sa("'C:/data/ras_1';'C:/data/ras_2'", outRaster) |
|
using r to make \t or \r not work. |
|
and thmUC=r"F:\data_processed\ltemp\tmp_UCras0" |
|
You tried also without r? I think it could be the problem... You can also
try replacing \ with / as iirc they are replaceable.

Okay, perhaps there is something wrong with 10.2.
Could you try something in this manner:
outCombine = Combine(["filter", "zone", "source.img", "dec.tif"])
outCombine.save("C:/sapyexamples/output/outcombine2")
So in this case it would be just
outCombine = arcpy.Combine( Wts_Rasters);
outCombine.save( outRaster )

I had a hard time running the logistiregression.py script. The main problems were:
some of these problems have already been reported in this post. Here are the script modifications i need to do:
Running on ArcMap 10.5.1 |

Thank you for your thorough analysis and debugging on this issue! I will
try this out ASAP and hopefully incorporate this fix into next version.

I had a hard time running the logistiregression.py script.
The main problems were:
- Arcmap crashes when running AddJoin_management function
- Files are not correctly identified
- Some unecessary lines giving error
- con_sa () function giving error
some of these problems have already been reported in this post.
after a lot of work, I was able to solve the problems and finally run the
script successfully.
Here are the script modifications i need to do:
- added on line 25 the import of spatial analyst functions
from arcpy.sa import *
- modified the lines 94 and 95:
Input_Rasters[i] = s.strip("'"); if
arcsdm.common.testandwarn_filegeodatabase_source(s.strip("'")):
- modified lines 141 to 148 :
Temp_Raster = gp.CreateScratchName('tmp_rst', '', 'rst',
gp.scratchworkspace) gp.copyraster_management(Input_Raster, Temp_Raster)
gp.JoinField_management(Temp_Raster, 'Value', Wts_Table, 'CLASS')
gp.AddMessage('Temp_Raster: %s'%(str(Temp_Raster)))
gp.Lookup_sa(Temp_Raster, "GEN_CLASS", Output_Raster)
- commented the lines 461, 462, 464, 466
strLine = fLR.readline() #vTabUCrows =
workarounds_93.rowgen(gp.SearchCursor(vTabUC)) #vTabUCrow =
vTabUCrows.Next() #ttl = 0 #while vTabUCrow: #for vTabUCrow in vTabUCrows:
ttl += 1
- comment line 582:
#gp.makerasterlayer_management(cmb, cmbrl)
- modified lines 587 to 589:
cmb_cpy = gp.createscratchname("cmb_cpy", '', 'raster',
arcpy.env.scratchFolder) gp.copyraster_management(cmb, cmb_cpy)
gp.JoinField_management(cmb_cpy, 'Value', tbltv, 'ID')
- modified lines 607 to 609:
outcon1 = Con(cmb_cpy, Lookup(cmb_cpy,"LRPOSTPROB"),"0","LRPOSTPROB >
0") outcon1.save(outRaster1) outcon2 =
Con(cmb_cpy,Lookup(cmb_cpy,"LR_STD_DEV"),"0","LR_STD_DEV > 0")
outcon2.save(outRaster2) outcon3 =
Con(cmb_cpy,Lookup(cmb_cpy,"LRTVALUE"),"0","LRTVALUE > 0")
outcon3.save(outRaster3)
Running on ArcMap 10.5.1

Could you send me the fixed .py file here as attachement? Others could benefit from your valuable work! |
|
Here is the file, code needs cleaning of some unecessary commented lines. |
|
Update on this issue: I think I haven't yet merged the code - we had summer holidays and some computer related problems. Will need to check and do when smoke clears. |
|
Hi, merged these changes - if you have time, please test if it went correctly. |
Hello, |
|
Can you help me please to solve this problem |
What inputs are you using? |

This was the error message. I Have used Arsdm many times before with no problem. and when I bring the old data and run logistic regression with those old data it works.. I wonder if there is any restriction on the study area surface? |

Sometimes it gives this 2nd error |
|
There is no restriction that I know of, but the tools seemed to be picky sometimes. Can you do operations fine on them manually? Unfortunately I have no clue on the cause. Anyone else? |
|
Hello, try to set workspace and scratch workspace to same folder. |
|
Load the newest version of ArcSDM (V5.02) and test again. If the problem persists, reopen this issue. |
