Error running L38 with python 3.6.3 #12

Closed robbietuk closed 5 years ago

robbietuk commented 5 years ago

I ran into an error with executing this line on my mac - Python 3.6.3

https://github.com/UCL/STIR-exercises/blob/e5ab1f58baa9d477a538c96a88da59e0e9256001/python/projection_demo.py#L38-L40 produced the error:

NotImplementedError: Wrong number or type of arguments for overloaded function 'ProjDataInfo_ProjDataInfoCTI'. Possible C/C++ prototypes are: stir::ProjDataInfo::ProjDataInfoCTI(stir::shared_ptr< stir::Scanner > const &,int const,int const,int const,int const,bool const) stir::ProjDataInfo::ProjDataInfoCTI(stir::shared_ptr< stir::Scanner > const &,int const,int const,int const,int const)

I believe this is because https://github.com/UCL/STIR-exercises/blob/e5ab1f58baa9d477a538c96a88da59e0e9256001/python/projection_demo.py#L35 produces type float where stir::ProjDataInfo::ProjDataInfoCTI only accepts integers.

This was only an issue on my Mac with python 3.6.3, the visual machine, running python 2.7.1 does not have this issue and num_views is an int.

I have resolved this issue by forcing num_views to be type int.
