My company uses Anaconda python, so I’m trying to use pyjulia. I tried building a system image following the instructions in the [docs](https://pyjulia.readthedocs.io/en/latest/sysimage.html), and ran into a segfault:

```julia
(pyjulia) evans-mbp:pyjl_test evan$ which python3
/Users/evan/anaconda3/envs/pyjulia/bin/python3
(pyjulia) evans-mbp:pyjl_test evan$ otool -L /Users/evan/anaconda3/envs/pyjulia/bin/python | grep libpython
(pyjulia) evans-mbp:pyjl_test evan$ python3 -m julia.sysimage sys.dylib

```
