Can Someone help me with this error, I have scikit-image already installed in my system, and my python script also running fine using cmd.

Hi @roopali_jain

This may help you!!!

Python Activity Troubleshooting

Step-A: (Validate the Configuration parameters) Check the Python exe file path location is properly specified in Python Scope properties Check the installed Python version is 64-bit or 32-bit. In case of 32-bit version select x86 Specify the Python version installed. It is always better to specify the Python version rather selecting Auto. [image] Step-B: Instead of using " Run Python Script " activity, use Load Python Script → Invoke Python Method → Get Python Object . Remove the Print …

Thanks!!
Happy Learning!!

@roopali_jain

Is in your environment do you have one or more python versions installed?

If so, then switch to 3.6 and install scikit-image

OR you can share your flow which you are getting error

Thanks

[roopali_jain]

I have tried this already, still issue persists

[roopali_jain]

I have installed python 3.9, is it needed to install 3.6 ?

[Srini84 (Srinivas Kadamati)]

@roopali_jain

Previously UiPath Python scope has upto 3.6 only, but now it got update to 3.9 also, but you can try using a sample script and try to run, If the error then share the screenshot, else you have check with the installation of the module

Thanks

[roopali_jain]

I have uninstalled python 3.9 also and switched to python 3.6.8 even though facing same issue. Attached is the error snapshot. Please let me know you comments…
Is there anything I’m missing?
Yes, even I tried small incrementing number example using python script which doesn’t contains any packages import like scikit-image, its running and working fine, so there is no issue with installation module. This error is coming when i am using skimage imports in my python script which basically working fine with vsCode and cmd.

Thanks in advance

Hi @Srini84 ,

I think, m doing some mistake in passing parameters to the python method using UIPath, I need to pass 2 arguments with images path. Can you help me with this:
syntax of python method: def snapCompare(benchmark,output, algorithm=“kmeans”, threshold=0.1): I am passing like this:

Thanks
