About Pickle's Import Error in Pyramid Application

[Yang Yang]

Hi All,

I've encountered a problem with Pickle's load function.

I have the following code in an request handling part:

      

class Test():

    def __init__(self,name):

        self.name=name

@view_defaults(route_name='test')

class test_view(object):

        ...

        f = open('test.pkl', 'rb')

        self.test = pickle.load(f)

        f.close()

So far it works alright. 

However, when I move the class Test code to a separate file test.py

and use "import test" to import the module.

The pickle reports that it cannot find test module.

When I use the code in CherryPy, it works fine.

Could anyone help me to solve the problem?

 

best regards

Yang

I solved the problem.

It has to do with Pickle package.
