Run a C# function from Python using Python.NET from https://pythonnet.github.io/pythonnet/python.html Call csharpfrompython.py which first calls the compiler and then calls the functions, feature request of better compiler bindings at https://github.com/pythonnet/pythonnet/issues/2196 ; includes two examples of NumPy -> C# array marshalling
namespace CSharpFromPythonNamespace
{
public class CSharpFromPythonClass
{
public string Hi(string x)
{
return "Hi " + x;
}
public static string Hello(string x)

How to contact Upwork.com support if you are hitting errors "Too many redirects" / "Unable to retrieve organization information" when creating a new Upwork account
This Upwork bug has been present for years and Upwork does nothing to fix it or even investigate it:
- https://community.upwork.com/t5/Freelancers/I-can-t-log-in-ERR-TOO-MANY-REDIRECTS/m-p/710733
- https://community.upwork.com/t5/Support-Forum/Invited-colleague-cannot-log-in-to-Upwork/td-p/1154335
In this situation, you cannot log in, and thus cannot even create a normal support ticket.
It seems that the problem appears because Upwork put account-> company association in an invalid state,
and thus something blows up when Upwork tries to fetch the account's company information during login.
I found a few ways to reach Upwork's Support even if you cannot log in:
- Create a support ticket about account/password recovery: https://support.upwork.com/hc/en-us/requests/new?ticket_form_id=360000464433
