Without knowing more about the "blitz" stuff, it is hard to provide detailed help.
However, it looks like you have a template taking a non-typename as a parameter, which is not currently supported in Cython. In other words, the 1 in [double,1] is not a type name, and that causes Cython to give up. There is a pull request in progress to fix this issue on GitHub, but I'm not sure what the latest is on that.
