question about demo #34

I'm really interesting about codepy an pycuda, but i got some bug when i run python demo.py.

/home/a01/anaconda3/envs/pycuda/compiler_compat/ld: cannot find -lboost_python-py38
/home/a01/anaconda3/envs/pycuda/compiler_compat/ld: cannot find -lpython3.8m
collect2: error: ld returned 1 exit status

i have google about how to fix it but it doesn't work , and it same when i try pycuda/from-wiki python thrust_interop.py.

my computer enviroment:
ubuntu1804
conda virtual python:3.8
pycuda and codepy have been successfully installed
