I've written code which imports data from a file and creates a shape file, then uses "arcpy.Project_management" to create a second shape file with a specific spatial reference (an abbreviated version of the code is provided below; there are downstream steps after this point, but I am not going to get into specifics as it is not pertinent). On my local system, everything works fine. However I have recently been using ArcMap on sensitive data that can only be accessed in an external system that is "locked down", where permissions are highly restricted. Now when the program reaches the "arcpy.Project_management" step: > "arcpy.Project_management(newfcName, newfcNameProject, out_coordinate_system)" I get two "cannot acquire lock" messages in a row, and a failure to execute message that kills the program: "Error 999999: Error Executing Function. Cannot acquire a lock. Cannot acquire a lock. Failed to execute (Project)" Any ideas on why this is happening, I would be thankful. Note that this problem only occurs if running python within the ArcMap GUI. If run on the Python IDLE, the program runs without issue.  And here's an abbreviated version of the code below: import arcpy outpath = r"C:/PATH/TO/OUTFOLDER/" dataFile = "C:/PATH/TO/INPUT/input.csv" arcpy.env.overwriteOutput=True arcpy.env.workspace= outpath newfcName = "OriginalData.shp" newfcNameProject = "ProjectedData.shp" # Shapefile with the coordinate system of the coordinate data within input projectedexample = "ExampleData-in-Input-Coordinate-Format.prj" # creating table to be filled newfc = arcpy.CreateFeatureclass_management(outpath, newfcName, "POINT", "", "", "", projectedexample) arcpy.AddField_management(newfc, "X", "FLOAT", field_length = 50) arcpy.AddField_management(newfc, "Y", "FLOAT", field_length = 50) arcpy.AddField_management(newfc, "Data", "FLOAT", field_length = 50) arcpy.AddField_management(newfc, "Time", "TEXT", field_length = 20) # Reference Cursors cursor=arcpy.da.InsertCursor(newfc, ["X", "Y", "Data", "Time", "SHAPE@XY"]) # Read Input File a = open(dataFile,"r") inputF = a.readlines() for line in inputF:    mySplit = line.split("\t")    xCoordinate = float(mySplit[0])    yCoordinate = float(mySplit[1])    timeData = str(mySplit[2])    zValue = float(mySplit[3])    newRow = (xCoordinate, yCoordinate, zValue, timeData, (xCoordinate, yCoordinate))    cursor.insertRow(newRow) a.close() # Desired Spatial Reference out_coordinate_system = arcpy.SpatialReference('Projected Coordinate Systems/World/WGS 1984 World Mercator') # New Projection for better accuracy of downstream analysis arcpy.Project_management(newfcName, newfcNameProject, out_coordinate_system) ____________________________________________________________________ Thank you. ...

Recently, many of my Python scripts run through the Python window (in ArcMap v10.8.1) will not progress past the first step unless the Python window is clicked. When run (using the 'execfile' command or when loading the program), only the first step is performed. The notification for that step appears, but is much slower to appear/disappear than normal. The program will then not progress to the next step until the ArcMap window is clicked (the location of this click does not seem to matter). Background processing is enabled. The problem is not script-related (as it has occurred when using two different Python scripts) nor computer related (as it has occurred on two different systems). Oddly, this issue comes and goes. The same program can be run twice in succession, and the program will progress normally on the second run. Sometimes resetting ArcMap will fix the issue, and sometimes it won't. Obviously this is a major detriment to my automation efforts, so any help on this matter would be appreciated. ... View more

I have written Python code to perform the following (sample code attached): 1) import a tab-delimited coordinates file; 2) add this information into a '.shp' file; 3) convert the coordinate system of the '.shp' file into a projected coordinate system. However, when running this code through ArcMap, I've been experiencing issues on step (3) where the Projected output from the "arcpy.Project_management" command sometimes returns an empty result (there is no error message; ArcMap says the conversion occurred successfully). The problem seems linked to the size of the input file. I describe this (and other oddities) below: 1) The input files are of the exact same tab-delimited structure ('X_Coord   Y_Coord   Date   Data'), the only difference between them is the amount of data within them. One ~1500 line file converted fine, but I discovered that I could make this error occur when I manually removed lines of data in Notepad: reduction to 1002-1499 lines of data would still work properly, but reducing it to <= 1001 lines lead to an empty result (it didn't seem to matter which lines I deleted). But the number of lines where this error occurs isn't set to the suspicious ~1000 line threshold: A ~450 line file would return a blank output, but doubling this input file (making it ~900 lines) did properly get processed by the Project command. 2) In the majority of cases when this error occurs, the attributes of the input '.shp' file (from step (2) above) is also emptied after the Project step is called. Note that this issue does not happen if the Project command is comment out (in other words, the data was there before Project was called). Despite being empty, if I use the "zoom to layer" command, ArcMap does zoom in to the proper region (even though it isn't displaying any information, it's still there in some capacity; this is not true for the Projected output however). 3) As I mentioned earlier, there is no error message. ArcMap acts as if the "arcpy.Project_management" step was successful. 4) These troublesome input files will converted just fine when processing these files manually through ArcMap (these steps being: 'Add Data' > 'Display XY Data' > 'Save as a Shape File' > 'Project' tool). But if I run my program (without the Project command), and then try to manually use the Project command within ArcMap itself on the input generated by my code, the error occurs, which seems to indicate this issue may be on how the input file is set up, and not the Project command itself. Any help would be most appreciated, thank you! Apologies if this was far too much detail. EDIT - some progression on the problem 1. The problem does not occur when Editor mode turned on within ArcMap  2. When Editor mode turned off, I could fix the problem by exporting the input as a new shape file (the new shape file would no longer cause the issues the original shape file was experiencing) 3. When attempting to simulate this "export" fix programmatically (in ArcPy), the following functions did NOT work:  - "FeatureClasstoShapeFile" (empty output, no error) - "CopyFeatures" (empty output, error code '000117') - "Project_management" without changing the coordinate data (empty output, no error) - "RecalculateFeatureClassExtent" (input file becomes greyed out [with an !] and unusable in the Table of Contents) Well, I found a solution for now, but I'd love any ideas on why this issue was happening in the first place. ...
