TypeError:'NoneType' object is not callable

I have update the tvm to the latest(2020/04/27). After this, I run the code that convert pyorch model to tvm. But get error in the first like this:

Traceback (most recent call last):

I'm confused with that, I run these command line below to update tvm:

git pull
git submodule update
cd build
cmake ..
make -j8

It is likely that you will also need to update your cython module, by typing make cython3, for future questions, please open a new trouble shooting thread on https://discuss.tvm.ai/
