TypeError: GPToolDialog() takes at most 1 argument (2 given)

SurendranNeelakantan

I am using ArcGIS 10.22

An error is coming in the python window "TypeError: GPToolDialog() takes at most 1 argument (2 given)"

But the tool seems working fine

The documentation says : GPToolDialog(toolbox, tool_name)

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

Does anyone know the reason ?

Thanks

That work around doesn't work (at least in my case). I suspect that it is because the error is not actually raising an exception, therefore it cannot be trapped by the try. It simply logs an error without any actual real problems.

It's not a big deal, because the script continues to run fine. I would simply prefer it not to print spurious errors when an error hasn't actually occurred. 🙂

pass makes more sense in this context than printing a whitespace character or empty string. I don't see any point in printing an empty line in this context. pass is a Python no-op, so actually legitimately does nothing in a context where a statement is required. I think that print statement is an attempt at a no-op, but doesn't quite hit the mark, as it would generate an empty-ish line of text (which may not matter to some people, but might to others).

pass worked for me in 10.2 (it's been a while since I've worked with python addins...) but not for another user.

Meh, python addins are not supported in Pro so I stopped bothering with them.

with the except block being

print " "

from the link... the thread that it refers to is archived since it is so old. and it was found in 10.1 but windows 7

It's a longstanding bug NIM089253. The workaround is just to wrap the call in a try block:

<SPAN class="keyword token">try</SPAN><SPAN class="punctuation token">:</SPAN>
    GPToolDialog<SPAN class="punctuation token">(</SPAN>toolbox<SPAN class="punctuation token">,</SPAN> tool_name<SPAN class="punctuation token">)</SPAN>
<SPAN class="keyword token">except</SPAN> TypeError<SPAN class="punctuation token">:</SPAN>
    <SPAN class="keyword token">pass</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

I'm getting the same error using ArcMap 10.5.1. I have Python Add-In with several tools which invoke pythonaddins.GPToolDialog() . In all cases they work perfectly well, but print out this error to the Python console:

TypeError: GPToolDialog() takes at most 1 argument (2 given)

I reckon it's a bug as the documentation clearly states that the function takes 2 arguments and it works fine with 2 arguments AND it doesn't appear to be a real problem as the tools all run perfectly well.

(I have a python console open sometimes for diagnostic purposes when developing and running these tools which use 'print' commands to log their progress.)

a small python window was docked by default . That is the reason I noticed this issue. Only once I received the error in a message box. I am closing the python window for the time being.

I am still wondering the GPToolDialog() need two argument then why the error message says "at most 1 argument"

The error message it self is wrong ? Do you think it could be a bug ?

Thank you

Just curious as to why the python window would be open? Are you editing then running the tool from the toolbar without closing the python window? If it works totally fine with the window closed, then forget about

I am not sure if the python toolbox is the problem. I am calling tool from a python toolbox . Tool works fine from tool bar button. The above error message is only visible if python window is open in Arcmap. This error not preventing the tool execution. May be I can Ignore this.

Thank you

From the thread I posted, I notice that they are using a toolbox (ie *.tbx)

toolPath = relPath + r"\Custom Tools\Get IR Count\Install\GetIR.tbx"

and you are using a python toolbox

toolboxPath = os.path.join(os.path.dirname(__file__), toolboxName + ".pyt")

could that be the difference? You might be advised to consult the section on python toolboxes again since their behaviours differ in some respects.

Does the toolboxPath variable contain any spaces?

I am using 10.22

Here is the code to call the Dialog

import arcpy

import pythonaddins

import os.path

class ButtonBuildGDB(object):

def __init__(self):

self.enabled = True

self.checked = False

def onClick(self):

toolboxName = "GDBAutomation_DRAFT"

toolName = "BuildGDB"

toolboxPath = os.path.join(os.path.dirname(__file__), toolboxName + ".pyt")

pythonaddins.GPToolDialog(toolboxPath, toolName)

Thanks

DanPatterson_Retired

No clue...other people haven't reported errors

https://community.esri.com/message/392058?sr=search&searchId=4b22ed49-a83c-4de1-be96-7e8db45afe9c&searchIndex=0#392058‌

show us the path and toolbox name...however, I doubt that is the problem since you said the tool operates.

What version are you using? I can find no bugs listed except for version 10.2.2 being modal

Thanks for the reply

Yes Tool Dialog is showing up and executing .

I am using the following line

pythonaddins.GPToolDialog(toolboxPath, toolName)

Where toolbox path and toolbox name are variable pointing to the correct path.

My question is Why the error says "at most 1 argument" where it supports 2 arguments.

thank you

DanPatterson_Retired

Is it in the format of the last line of that help?

pythonaddins.GPToolDialog(r'C:\MyTools\WaterStudy.tbx', 'GroundWaterYield')

note the raw notation to the tbx name.

JasonScheirer

Is the tool dialog showing up? If not, are you sure you're passing in the correct path to the TBX and the correct Tool Name?
