Just to confirm, you're still seeing the error message to change how the Dash libraries are being imported within your Python script? Or you are still seeing the pandas numpy error?
Thanks,
Jason

Jason,
It starts out with the Dash error stating it is decpreciated (ver 2.6.0) and then it seems to go into the pandas problem and back to the commend prrompt. I've placed the problem below

This is the same error whether the version of Dash is 2.6.0 or 1.21.0

I'm comfortable enough to go in and change things to the Dash 2.0 import statements. I give that a go and report back. I'll backup the script first!! Thanks Scott |

OK, Fooling around with the dash app, it appears to be cleaned up and now is leaving the problem with the pandas app. Below is the error

I think I've fixed the problem. I uninstalled pandas and re-installed and it seems to work. I think it installed a newer version as well.   |

I found success installing pandas using the apt package python3-pandas instead of pip installing pandas. Glad to see its working for you! Thanks, Jason |

Thanks for the help, both of you. Now I need to move on from Blynk and find something else. I see a few post around here on the subject.
