Spotfire VitroVivo: Issue installing built-in Python packages when using a proxy.

Using Revvity Signals VitroVivo and updating your packages in the app dependency manager you can run into an issue with the packages "signals_dimreduction" and "signals_spotfiremiddleware" as shown in the below screenshot:

This issue can occur if you need to define a proxy for downloading Python packages using pip.

The packages that have issues are not delivered from the pip repository and are installed from local packages and this combination will make the installation of the local packages to fail.

To install the packages you can do the following workaround:

1.From a Windows command prompt move to the path where the  Revvity Signals Python packages are locally available, (note that the version numbers can be different)

 
C:\> cd <Path to Spotfire Analyst client>\Modules\Signals VitroVivo Product_4.0.14.10861\spotfire resources\Python packages\Python_311

 2. Check that signals_dimreduction-1.0.8-py3-none-any.whl and signals_spotfiremiddleware-1.0.8-py3-none-any.whl Python packages exist at the current path.

3. Install the packages specifying proxy info:
 
python.exe -m pip install --proxy=<http://<proxyserver>>:<port> signals_dimreduction-1.0.8-py3-none-any.whl

python.exe -m pip install --proxy=<http://<proxyserver>>:<port> signals_spotfiremiddleware-1.0.8-py3-none-any.whl

Note if the version numbers differ, change them to match the exact version that you see in your environment.
