I'm using TDengine database to process time-series data. My application is developed by Python.
I imported the Python connector of TDengine. I encountered an error while loading the python module.
taos.error.InterfaceError: [0xffff]: unable to load taos C
library:Could not find module taos (or one of its dependencies)
I don't know how to fix it.
I checked the documentation, but no solution was found.

I'm trying to create snowpark UDF in python as object. Below is my code
from snowflake.snowpark.functions import udf
from pytorch_tabnet.tab_model import TabNetRegressor
session.clearImports()
model = TabNetRegressor()
model.load_model(model_file)
lib_test = udf(lambda: (model.device), return_type=StringType())
I'm getting a error like below
Failed to execute query

002072 (42601): SQL compilation error:
Unknown function language: PYTHON.
It throws error as python is not available.
I checked the packages available in information schema. It shows only scala and java. I'm not sure why python is not available in packages. How to add python to the packages? adding python will resolve this issue?
can anyone help on this? Thanks
The Python UDFs are not in production yet and are only available to selected accounts.
Please reach to Snowflake account team to have the functionality enabled.
I'm trying DolphinDB python API to subscribe a stream table from our DolphinDB cluster. But as I run import dolphindb it reports
ImportError: DLL load failed: The specified module could not be found.
As I read the readme for a second time, I found that only Anaconda python is supported, because of some issue of DLL loading.
But I cannot use Anaconda for some reason, so is there any workaround?
The c++ version python api is based on DolphinDB's c++ api. On windows platform, c++ api is compiled by mingw so that the runtime requires mingw's core dll. The non-Anaconda doesn't come with mingw runtime and hence failed to import the DophinDB python api.
The new version of python api has included mingw's required libraries. Please check it out.
I am trying to create Python UDF in Amazon Redshift, and I have successfully created the UDF with no error. I have also created the required library for this UDF successfully. But when I execute the UDF, I get the error:
No Module Named pyffx. Please look at svl_udf_log for more information
I have downloaded the library from pypi.org and uploaded it to Amazon S3. This is the link I used to download the library:
https://pypi.org/project/pyffx/#files
create library pyffx
language plpythonu
from 's3://aws-bucket/tmp/python_module/pyffx-0.3.0.zip'
credentials
'aws_iam_role=iam role'
region 'us-east-1';
CREATE OR REPLACE FUNCTION schema.ffx(src VARCHAR)
RETURNS VARCHAR
STABLE
AS $$
import pyffx
src = unicode(src)
value=(src)
l=len(value)
e = pyffx.String(b'secret-key', alphabet='abcedefghijklmnopqrstuvwxyz123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', length=l)
return e.encrypt(value)
$$ LANGUAGE plpythonu;
I managed to get it to work... sort of.
I did the following:
Downloaded pyffx via the link you provided
Extracted the .tar.gz file and created a .zip of the files
Copied the .zip file to Amazon S3
Loaded the library using your CREATE LIBRARY command
Created the function
However, when I use the function, I receive the error:
Invalid operation: AttributeError: 'module' object has no attribute 'add_metaclass'
My research suggests that the six library (that provides Python 2 and 3 compatibility) is the source of this problem. The Python Language Support for UDFs - Amazon Redshift page indicates that six 1.3 is included in Redshift, yet Pip six.add_metaclass error says that this version does not include add_metaclass. The current version of six is 1.12.
I tried to include an updated six library in the code but wasn't successful. You might be able to wrangle better than me.
ImportError: No module named Processing
I am using QGIS APIs for developing my application in Python. Eclipse is the IDE that I have been using for other projects. Now, I am trying to connect eclipse to the packages and libraries of QGIS but it is not going well.
the error I currently get is:
ImportError: No module named Processing
I have included all libraries, packages, DLLs and so on.
below you can see a snapshot of a piece of my code.
I have no idea how to fix it.
I have checked this configuration as well.
I also read almost all the related topics in the stackoverflow...I set the processing in my python path (both in the beginning and at the end)..
I have been restarting my system every time I changed the setting...
what is wrong!
To work with processing package, you should add it in a level higher than processing package like:
C:\OSGeo4W\apps\qgis\python\plugins
where processing is in plugins. then import processing will perfectly work.
i've built a com component which utilizes libxml2 python bindings , the build is successfull but when i try to register the component i get "specified module could not be found , unable to load python dll" this is the error i get when the component is built using the bundle files option set as 1
if i build the component with bundle files set as 3 ,then i get a different error saying that the component was loaded but the call to DllRegisterServer Failed with error code 80040201
if the libxml2 import is removed all works fine.
any help wold be simply great.
thanks
Most likely, regsvr32.exe which registers you COM component couldn't find a DLL that your COM component needs.
I'm not familiar with Python COM components but is there some way you can run depends.exe on it? This is the usual way to track down binary dependency problems.
