Problem importing ROOT from python session

ROOT
1

Hello

While ROOT and pyroot work fine if I initialize them, however I cannot call ROOT from withing python session

python
Python 2.7.16 |Anaconda, Inc.| (default, Sep 24 2019, 16:55:38)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ROOT
Fatal Python error: PyThreadState_Get: no current thread
Abort trap: 6

Any ideas ?

TIA

Hi,

Please let us know the output of root --version and root-config --features. I’m not sure I understand what you mean by “initializing”, could you explain?

Cheers,
Jakob

Hi,

I am using root-12-04.

The config-features returns this list :
asimage astiff bonjour builtin_afterimage builtin_cfitsio builtin_davix builtin_fftw3 builtin_freetype builtin_ftgl builtin_gl2ps builtin_glew builtin_gsl builtin_llvm builtin_lzma builtin_lz4 builtin_openssl builtin_pcre builtin_tbb builtin_unuran builtin_xrootd cling cocoa cxx11 davix exceptions explicitlink fftw3 fitsio fortran gdml genvector http imt krb5 ldap libcxx macos_native mathmore memstat minuit2 opengl pch python roofit shared sqlite ssl table thread tmva unuran xml xrootd

Thanks
Alexis

The version number looks odd, is root-12-04 the exact output of root --version?

Sorry , it 6-12-04

Thanks! PyROOT received some substantial updates meanwhile which might have fixed the issue. Would it be possible for you to update to the latest ROOT 6.22?
