How to print out error information when debugging PyJulia?

There seems to be some incompatibilities between PyJulia and other packages, and I would like to do some debugging:

first do `import ` then
```
import julia
j = julia.Julia()
```
would crash the Python kernel (in Jupyter notebook) or give "Segmentation Fault" (in terminal); on the other hand, first do
```
import julia
j = julia.Julia()
```
then `import ` gives no error.

I suspect the package might interfere with the communication between Python and Julia, but the error message isn't printed out to Python so that I can't debug. Any idea how to print out the error messages, or hints on why the error occurs? Thanks!
