I have been trying to control a camera through a wsdl file using SUDS. I have got the code working but I want to place error handling into the script. I have tried different exceptions but am unable to get the script working. When I enter an invalid coordinate I get an error. The code I am using is below followed by the error I am recieving.

suds.WebFault: Server raised fault: 'Error setting requested pan'
I am not sure which exception I should be using here. Does anyone know how to catch this error. The x coordinate with the value 400 is in degree's that is why the error happens.
Thanks
Okay I have found the solution. In SUDS if you enter:
faults=False
into the client definition, this catches faults and gives the reason why the fault happened. The line should read:
client = Client('http://file.wsdl', faults=False)
The post that I have marked as the correct answer also is able to catch that a problem has happened.
Thanks all
If you handled all exceptions and errors in your code and your code is working fine but still you are getting below message with your correct output.
Msg : "No handlers could be found for logger suds.client "
Then a simple solution is to add this line
logging.getLogger('suds.client').setLevel(logging.CRITICAL)
in yourclient.py file just after all import statement.
If you want to catch that exception you should put
try:
result = client.service.AbsoluteMove(token, dest, speed)
except suds.WebFault as detail:
...
You need to catch suds.WebFault by the looks of that traceback. The error itself seems legitimate, IE, your requests are being executed correctly, but perhaps your parameters are wrong in the given context.
I believe you refer to a harmless diagnostic message in your comment. I could suppress messages from suds calling logging.error() by assigning logging.INFO to basicConfig and logging.CRITICAL to suds.client.

I've been trying to follow the examples and documentation for the python ad_manager library for the google ads API, but I haven't been able to complete a successful request. I currently have my developer token, client_id, client_secret, and refresh_token in my google ads YAML file, but I'm constantly getting the error "argument should be integer or bytes-like object, not 'str'" when calling the function WaitForReport following the example code below. I was wondering if anyone had any advice on how I could tackle this issue.
import tempfile
# Import appropriate modules from the client library.
from googleads import ad_manager
from googleads import errors
def main(client):
# Initialize a DataDownloader.
report_downloader = client.GetDataDownloader(version='v202111')
# Create report job.
report_job = {
'reportQuery': {
'dimensions': ['COUNTRY_NAME', 'LINE_ITEM_ID', 'LINE_ITEM_NAME'],
'columns': ['UNIQUE_REACH_FREQUENCY', 'UNIQUE_REACH_IMPRESSIONS',
'UNIQUE_REACH'],
'dateRangeType': 'REACH_LIFETIME'
}
}
try:
# Run the report and wait for it to finish.
report_job_id = report_downloader.WaitForReport(report_job)
except errors.AdManagerReportError as e:
print('Failed to generate report. Error was: %s' % e)
# Change to your preferred export format.
export_format = 'CSV_DUMP'
report_file = tempfile.NamedTemporaryFile(suffix='.csv.gz', delete=False)
# Download report data.
report_downloader.DownloadReportToFile(
report_job_id, export_format, report_file)
report_file.close()
# Display results.
print('Report job with id "%s" downloaded to:\n%s' % (
report_job_id, report_file.name))
if __name__ == '__main__':
# Initialize client object.
ad_manager_client = ad_manager.AdManagerClient.LoadFromStorage()
main(ad_manager_client)

Below is the stack trace:

In your YAML file, do you have your account number in quotes? (either single or double?)
Additionally, I would highly recommend not going with this API if you have the option. It will be sunset in April and will no longer work. The newer google ads API (as opposed to the AdWords API) is available, stable and much easier to work with. The ad manager examples are good too.
The problem seems to be that zeep raises a WebFault which includes the returned XML response as a string in zeep.Fault.detail.
Somewhat counter-intuitive, this attribute is not a string, but a bytes sequence because zeep.wsdl.utils.etree_to_string calls etree.tostring() with encoding="utf-8" instead of encoding="unicode"—the latter would make sure it's a proper string.
googleads then tries to look for specific error strings inside the XML using find(), but even though find() is defined both on str and bytes, the type of the substring to look for needs to align.
Thus, in
underlying_exception = e.detail.find(
'{%s}ApiExceptionFault' % self._GetBindingNamespace())
bytes.find() is called with a str argument, causing the ValueError you experience.
I'd argue that zeep.wsdl.utils.etree_to_string() should be adjusted to actually return a str instead of bytes. You could try opening an issue on Zeep's Github repository.
I am using a peaktech 4046 : 160MHz Function/arbitrary Waveform Generator. I developping on pyton and I am using the pyvisa librairy.
The connection is well established and the generator applies the query. But it generates the following error and stops the program (it doesn't do anything after the error).
Here is the code :
import pyvisa
rm = pyvisa.ResourceManager()
inst = rm.open_resource('TCPIP0::130.79.192.123::5025::SOCKET')
print(inst.session)
print(inst.io_protocol)
inst.query("source1:function squ")
And here is what I have in my terminal :

raise errors.VisaIOError(rv)
pyvisa.errors.VisaIOError: VI_ERROR_TMO (-1073807339): Timeout expired before operation completed.
I have tried (to no avail) :
-changing SOCKET to INSTR
-using a timout much longeur ( inst.timeout = 10000)
-adding a end term (tried \n and \r) with : inst.read_termination = '\n'
So I don't know what to do anymore... I need to give more than one command, so the program must not stop so fast. I suspect that my function generator is not sending anything back, but I don't know how to make sure this is the case.
What I wish to know is : Why do I have a time out error if the connection is well established and the request is executed on the device ? How to do the request in a proper way ?
Thank you in advance !!
PS : I know how to catch the error (with try except) but I'd rather have an Ok answer thant a KO one.
Try to get a list of resources by
rm.list_resources()
and check that your resource TCPIP0::130.79.192.123::5025::SOCKET in it.
Then check the standard request to the resource from tutorial:
inst.query("*IDN?")
query is a short form for a write operation to send a message, followed by a read. So you could do this in two actions to specify the error(read or write error?):
inst.write('"source1:function squ"')
print(inst.read())
Please, check the name of query source1:function squ because I don't see it in the documentation. Maybe you should use "source1:am:interanal:function square(p. 57 of documentation) or change squ -> square?
Accordingly documentation, you could try to set infinite timeout to your request by
del inst.timeout
Also, you could add read_termination/write_termination option to specify when you'll finish your reading/writing by
inst = rm.open_resource('TCPIP0::130.79.192.123::5025::SOCKET', read_termination='\r')
And the last chance is changing the options query_delay and send_end.
i'm a newbie in python and coding,i'm trying to use pyzabbix to add trigger dependecies,but some error occusrs.
When i run
zapi.trigger.addDependencies(triggerid, dependsOnTriggerid)
an error occurs
pyzabbix.ZabbixAPIException: ('Error -32500: Application error., No permissions to referred object or it does not exist!', -32500)
i get the "triggerid" and "dependsOnTriggerid" by trigger.get:
triggerid_info = zapi.trigger.get(filter={'host': 'xx','description': 'xx'},output=['triggerid'], selectDependencies=['description'])
triggerid = triggerid_info[0]['triggerid']
dependsOnTriggerid = trigger_info[0]['dependencies'][0]['triggerid']
The results are as follws:
Traceback (most recent call last): File "E:/10.python/2019-03-07/1.py", line 14, in zapi.trigger.addDependencies(triggerid, dependsOnTriggerid) File "D:\Program Files\Python37\lib\site-packages\pyzabbix__init__.py", line 166, in fn args or kwargs File "D:\Program Files\Python37\lib\site-packages\pyzabbix__init__.py", line 143, in do_request raise ZabbixAPIException(msg, response_json['error']['code']) pyzabbix.ZabbixAPIException: ('Error -32500: Application error., No permissions to referred object or it does not exist!', -32500)
Did i get the wrong triggerid? or the i use the method in a wrong way? Thanks so much
To add a dependancy means that you need to link two different triggers (from the same host or from another one) with a master-dependent logic.
You are trying to add the dependancy triggerid -> dependsOnTriggerid, which is obtained from a supposed existing dependancy (trigger_info[0]['dependencies'][0]['triggerid']), and this makes little sense and I suppose it's the cause of the error.
You need to get both trigger's triggerid and then add the dependancy:
masterTriggerObj = zapi.trigger.get( /* filter to get your master trigger here */ )
dependentTriggerObj = zapi.trigger.get( /* filter to get your dependent trigger here */)
result = zapi.trigger.adddependencies(triggerid=dependentTriggerObj[0]['triggerid'], dependsOnTriggerid=masterTriggerObj[0]['triggerid'])
The method "trigger.addDependencies" need only one parameter，and it should be a dict or some other object/array.The following code solves the problem.
trigger_info = zapi.trigger.get(filter={xx},output=['triggerid'])
trigger_depends_info_193 = zapi.trigger.get(filter={xx},output=['triggerid'])
trigger_dependson_193 = {"triggerid": trigger_info[0]['triggerid'], "dependsOnTriggerid": trigger_depends_info_193[0]['triggerid']}
zapi.trigger.adddependencies(trigger_dependson_193)
I've created a standalone exe Windows service written in Python and built with pyInstaller. When I try to import wmi, an exception is thrown.
What's really baffling is that I can do it without a problem if running the code in a foreground exe, or a foreground python script, or a python script running as a background service via pythonservice.exe!
Why does it fail under this special circumstance of running as a service exe?

Note: I tried using
pythoncom.CoInitialize()
which apparently solves this import problem within a thread, but that didn't work...
I also face the same issue and I figure out this issue finally,
import pythoncom and CoInitialize pythoncom.CoInitialize (). They import wmi
import pythoncom
pythoncom.CoInitialize ()
import wmi
I tried solving this countless ways. In the end, I threw in the towel and had to just find a different means of achieving the same goals I had with wmi.
Apparently that invalid syntax error is thrown when trying to create an object with an invalid "moniker name", which can simply mean the service, application, etc. doesn't exist on the system. Under this circumstance "winmgmts" just can't be found at all it seems! And yes, I tried numerous variations on that moniker with additional specs, and I tried running the service under a different user account, etc.
Honestly I didn't dig in order to understand why this occurs.
Anyway, the below imports solved my problem - which was occurring only when ran from a Flask instance:
import os
import pythoncom
pythoncom.CoInitialize()
from win32com.client import GetObject
import wmi
The error "com_error: (-2147221020, 'Invalid syntax', None, None)" is exactly what popped up in my case so I came here after a long time of searching the web and voila:
Under this circumstance "winmgmts" just can't be found at all it
seems!
This was the correct hint for because i had just a typo , used "winmgmt:" without trailing 's'. So invalid sythax refers to the first methods parameter, not the python code itself. o_0 Unfortunately I can't find any reference which objects we can get with win32com.client.GetObject()... So if anybody has a hint to which params are "allowed" / should work, please port it here. :-)

UnpicklingError: unpickling stack underflow –
The fact that your exceptions always happen when you try to access the pickled data seem to indicate that you are hitting a bug in the cPickle library instead.
What can happen is that a C library forgets to handle an exception. The exception info is stored, not handled, and is sitting there in the interpreter until another exception happens or another piece of C code does check for an exception. At this point the old, unhandled exception is thrown instead.
Your error is clearly cPickle related, it is very unhappy about the data you feed it, but the exception itself is thrown in unrelated locations. This could be threading related, it could be a regular non-threading-related bug.
You need to see if you can load the data in a test setting. Write wrapPacked to a file for later testing. Load that file in a interpreter shell session, load it with cPickle.loads() and see what happens. Do the same with the pickle module.
If you do run into similar problems in this test session, and you can reproduce it (weird exceptions being thrown at a later point in the session) you need to file a bug with the Python project to have this looked at.
