CHYBA 000354 při volání Connect Public Transit Data Model To Streets v python skriptu

One further thought (after looking at the tool code): Try printing the value of arcpy.env.scratchGDB in your code and see what it points to. Delete it, and try running the script again. I've seen cases where the scratch gdb gets corrupted, and then weird things happen.

Possibly it works when you run the tool in the Pro UI because it's pointing to a different scratch gdb.

"I wish I knew how exactly the scratch gdb was possibly corrupted"

Me too! I'd love to get that fixed on our end.

Glad that worked!!

JosephAhrenholtz1

That was it! After deleting scratch gdb the script ran successfully. I wish I knew how exactly the scratch gdb was possibly corrupted to avoid or help trouble shoot future issues. But in any case it worked. Thanks very much!

Ok yeah I'll keep troubleshooting and call support if needed. Thanks for taking a look.

JosephAhrenholtz1

Yeah, still the same error when replacing "Streets" with the full path to the fc.

Melinda Morang

Does the tool still error if you replace "Streets" with the full path to the streets feature class? Maybe the tool isn't correctly paying attention to the workspace environment set in the script.

JosephAhrenholtz1

Got it, appreciate the suggestion. I'm shifting from primarily using R so am still familiarizing myself with best practices in Python.

I've updated the code using the os.path.join() method, which required me to concatenate each level to build the full path. See in the code below:

# Imports
import arcpy
import os
import pandas as pd
from arcgis.features import GeoAccessor, GeoSeriesAccessor

# Paths
proj_dir = r"C:\Users\josephda\GitHub\osm"
streets_dir = os.path.join(proj_dir, "data", "raw", "Street_Centerlines", "Street_Centerlines.shp")
gtfs_dir = os.path.join(proj_dir, "data", "raw", "gtfs")
aprx_dir = os.path.join(proj_dir, "arcgis", "arcgis.aprx")
gdb_dir = os.path.join(proj_dir, "arcgis", "arcgis.gdb")
nw_dir = os.path.join(proj_dir, "arcgis", "arcgis.gdb", "TransitNetwork")

# Environment settings
arcpy.env.workspace = gdb_dir

# Set output coordinate system to NAD83 CA Albers
arcpy.env.outputCoordinateSystem = arcpy.SpatialReference(3310)

# Declare the project file
aprx = arcpy.mp.ArcGISProject(aprx_dir)

# List maps in the project
for m in aprx.listMaps():
    print(m.name)
    # List layers in the map
    for lyr in m.listLayers():
        print(lyr.name)
        # Remove any existing layers except the basemap
        if lyr.isBasemapLayer == False:
            m.removeLayer(lyr)
    aprx.save() 


# Load the streets shapefile as a spatially enabled dataframe
streets_sed = pd.DataFrame.spatial.from_featureclass(streets_dir)

# Create fc from streets sed
streets_fc_dir = os.path.join(gdb_dir, "streets_fc")
streets_fc = streets_sed.spatial.to_featureclass(streets_fc_dir)

# Add restrict pedestrian field
arcpy.AddField_management("streets_fc", "RestrictPedestrians", "TEXT")
arcpy.CalculateField_management("streets_fc", "RestrictPedestrians", "'Y' if !circulatio! == 'Freeway' or !circulatio! == 'State Route' or !road_type! == 'Railway' else 'N'", "PYTHON")
arcpy.AddField_management("streets_fc", "ROAD_CLASS", "SHORT")

# Create the feature dataset
arcpy.CreateFeatureDataset_management(gdb_dir, "TransitNetwork", arcpy.SpatialReference(3310))

# Covert GTFS to transit data model
arcpy.transit.GTFSToPublicTransitDataModel(gtfs_dir, nw_dir, "NO_INTERPOLATE", "NO_APPEND")

# Copy streets to TransitNetwork feature dataset as "Streets"
nw_streets_dir = os.path.join(nw_dir, "Streets")
arcpy.CopyFeatures_management("streets_fc", nw_streets_dir)

# Delete the other copy of streets
arcpy.Delete_management("streets_fc")

# Connect the transit data model to streets
arcpy.transit.ConnectPublicTransitDataModelToStreets(nw_dir, "Streets", "100 Meters", "RestrictPedestrians <> 'N'")

It throws the same error

Unfortunately, this update still throws the same 000354 error when connecting the transit model to streets (at line 62). If I replace line 62 with the following:

arcpy.transit.ConnectPublicTransitDataModelToStreets(r"C:\Users\josephda\GitHub\osm\arcgis\arcgis.gdb\TransitNetwork", "Streets", "100 Meters", "RestrictPedestrians <> 'N'")

It throws the same error. This makes me think the issue isn't rooted in the path construction, but I could be wrong.

Melinda Morang

Hmm, I'm not sure why you're getting that error based on what I see in the code. However, the one thing that jumps out at me is the way you're constructing filepaths in the Python script. It's safer to use os.path.join() to construct paths from multiple components rather than the + operator. It doesn't seem like the way you have them should cause an error, but it's not really the best coding practice.

Try updating like this, and see if that fixes it:

streets_dir = os.path.join(proj_dir, '\data\raw\Street_Centerlines\Street_Centerlines.shp')
