Import fails with root 6.08 release candidate

maxnoe opened this issue 8 years ago · 5 comments

Today I tried installing root_numpy with the relase candidate for 6.08 (python 3 bug fix)

When I try to import root_numpy, I get:

In [1]: import root_numpy

Building that ROOT release now to check

Actually, I'm not seeing this problem. Did you check that you in fact uninstalled root_numpy before building it from scratch again and reinstalling it?

Answer 3 · 2016-10-14T03:35:24.000Z

"undefined symbol" typically means it's still the old .so that was built against the previous version of ROOT you had.

I made sure I uninstall root_numpy. I also tried with a fresh conda environment.

Sorry, my bad. It was the pip cache. I had to reinstall with pip install --no-cache root_numpy. Uninstall is not enough as then only the already built wheel is used.
