Ni VeriStand Python

[sgray90]

Hey Marcelo, I am still having a little issue maybe you can take a look at the screenshot of my command prompt and tell me where I may have went wrong? 

Thanks

Hey sgray90,

It appears you have a space between the dashes and upgrade, so it is not seeing upgrade as a flag in pip. I saw the same error when adding the space. Try running "python -m pip install --upgrade niveristand" without the space between "--" and "upgrade".

Hey Andy,

I am still getting the same error message once I made those changes

[sgray90]

UPDATE!!! I figured out the solution it was a minor typo but I will keep you posted to let you know if I can run a script! Thanks again Andy

Good afternoon Andy, 

After we updated the NI VeriStand python integration packages our NI MAX GUI runs very slowly do you know why that would be possible?

Hi sgray90 

I would recommend starting by taking a look at the steps in this document as an initial troubleshooting point: 

Database Connection Error in Measurement & Automation Explorer (NI MAX)

UPDATES!!!! Recently, I have been able to fix the previous error. But now I am having issues with running the Python script for the engine demo in the command prompt.  I am receiving an error saying cannot find engine power channel. How can I fix this issue?

Hey sgray90,

Do you have the Engine Demo deployed to localhost? This is the first error you would receive when running the Engine Demo example script without the System Definition deployed.

I was able to reproduce your error without the System Definition deployed. Then, I deployed the System Definition, and it executed as expected.

I think it would be helpful to create a new forum post if have more questions with the Python API.

Thanks,

Andy
