Hi!
I have found the solution. Numpy and matplotlib have different FPU flags behaviour from Lazarus and Delphi. So import wasn't executed correctly due to "Floating point division by zero exception" (it wasn’t shown but it is the different problem). So I have used SetExceptionMask function to prevent "Floating point division by zero" exception. After that numpy and matplotlib became working correctly.
