Issues with python path

Question

I am working on a program in Arcgis however, I have a python issue. While trying to run the following script I am getting an invalid MXD error which seems to suggest that it cannot find the location of my MXD file.

# modified by ESRI for use as a toolbox script tool
## imported sys to get the raw inputs and os to use for path separator
import arcpy, sys, os
# Set OverWrite if files already exist
arcpy.OverWriteOutput = 1
print "Enter folder path:"
mapDoc = raw_input()
#mapDoc = sys.argv[1]
print os.path.dirname(mapDoc)
# set a variable to the full path and file name of the MXD
fullnam = os.path.basename(mapDoc)
# Strip off the MXD file extension and store as string variable for use in the 'out_pdf'
nam = fullnam.strip(".mxd")
print nam
# Commented this out, since it doesnt need to be a parameter when you use the MXD name as the PDF name
##print "Enter save as name:"
##mapName = sys.argv[2]
map = arcpy.mapping
mxd = map.MapDocument(mapDoc)
map_document = mxd
#out_pdf = r"K:\projects" + "\\" + mapName + ".pdf"
#out_pdf = r"K:\projects" + os.sep + mapName + ".pdf"
#out_pdf = os.path.dirname(mapDoc) + os.sep + mapName + ".pdf"
out_pdf = os.path.dirname(mapDoc) + os.sep + nam + ".pdf"
# Set all the parameters as variables here:
data_frame = 'PAGE_LAYOUT'
resolution = "300"
image_quality = "NORMAL"
colorspace = "RGB"
compress_vectors = "True"
image_compression = "DEFLATE"
picture_symbol = 'RASTERIZE_BITMAP'
convert_markers = "False"
embed_fonts = "True"
layers_attributes = "NONE"
georef_info = "False"
# Due to a known issue, the df_export_width and df_export_height must be set to integers in the code:
map.ExportToPDF(map_document, out_pdf, data_frame, 640, 480, resolution, image_quality, colorspace, compress_vectors, image_compression, picture_symbol, convert_markers, embed_fonts, layers_attributes, georef_info)
# This gives feedback in the script tool dialog:
arcpy.GetMessages()

Now please look at the command prompt.

(arcgispro-py3) C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3>"C:\Us
ers\ant\Documents\MyCensus_Files\Python script\Export2PDF.py"
Enter folder path:
C:\Users\ant\Documents\MyCensus_Files\Python script
C:\Users\ant\Documents\MyCensus_Files
Python script
Traceback (most recent call last):
 File "C:\Users\ant\Documents\MyCensus_Files\Python script\Export2PDF.py
", line 22, in <module>
 mxd = map.MapDocument(mapDoc)
 File "C:\Program Files (x86)\ArcGIS\Desktop10.6\ArcPy\arcpy\arcobjects\mixins.
py", line 651, in __init__
 assert (os.path.isfile(mxd) or (mxd.lower() == "current")), gp.getIDMessage(
89004, "Invalid MXD filename")
AssertionError: Invalid MXD filename.

As you can see, the path I enter is different from what is being returned by print and I think that is what's causing my issue. Would appreciate it anyone could assist fixing handling this path error or with a python script that accomplishes converting MXD to PDF.

• Richard: My advice would be to create a variable in your code that contains the path to the mapDoc file. filename = os.path.join("c:/", "path", "to", "the", "filename.mxd") and pass that to map.MapDocument(filename)
• Niana: @Richard but if i use that I will have to hardcode the .mxd file. I wanted to do it like a batch
• Richard: Sure, we can set up batch processing once we get a simple case working.
• Niana: filename = os.path.join("C:\Users\ant\Documents\MyCensus_Files\Python_script\test.mxd") fullnam = os.path.basename(filename) print filename I have changed it to the above and print shows me the mxd file but i still get the invalid error
• Niana: @Richard It works, but how can i convert everything in the folder vs doing it by sending the file name

Answer 1

If you print out mapDoc right before the line map.MapDocument(mapDoc), you would see that you're trying to pass C:\Users\ant\Documents\MyCensus_Files\Python script as a mxd file. That's a directory, not a mxd file.

• Niana: The idea was to pass the path where the MXD files are so that I can convert them all. But even when I hard code the file name, I still get the error
• Niana: it works, but how do I convert everything in the path instead of having to pass the file name?

Try this:

import arcpy, sys, os
arcpy.OverWriteOutput = 1
mapDoc = os.path.join("C:/", "Users", "ant", "Documents", "MyCensus_Files", "Python_script", "test.mxd") 
map = arcpy.mapping
mxd = map.MapDocument(mapDoc)
