The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs, defending the body against foreign bodies (antigens), such as bacteria, viruses and cancerous cells.There are two types of lymphocytes :B cells-produce antibodies which are released into the fluid surrounding the bodyâs cells to destroy the invading viruses and bacteria. T cells (see picture opposite) - if the invader gets inside a cell, these (T cells) lock on to the infected cell, multiply and destroy it.here are two types of lymphocytes : B cells-produce antibodies which are released into the fluid surrounding the bodyâs cells to destroy the invading viruses and bacteria.

It is the partial output from running PyInstaller and the Random error may have its origins in the processing of a PyInstaller hook file - but I'm guessing. I've had some luck resolving the no module named numpy, cannot import name <blah> type of errors. All cases are exemplified by this example ... The file Python2.7/tempfile.py is attempting to import random from the Standard Library but instead is importing the one from Numpy (numpy.random).
