How to call vertex ai script from php from a browser url on a linux or Mac server?

I am trying to call a vertex ai generated python script to generate text from a php page and invoke it from a browser url.

The python script does not work on a linux or Mac server(but works on windows) when invoked from php through the browser url.

Interestingly the script works in terminal.

I am calling the vertex ai python script from php like this:

$Output = shell_exec(“python3 vertex.py”);

print($Output);

I am looking for a way to run the python script from the browser when called or invoked from the php script on a linux or macOS Server.

I am thinking that the issue could be due to/linked to handling virtual environment using php when the python script is invoked from the browser using php.

Bottom line it could be linked to the following underlying issues:

1. How to handle google login/authentication for vertex scripts when called from the browser?

2. It could also be linked to the handling of the virtual environment using php or python.
