8 years ago Are you running the code under your pyUni10 directory? If so, move to another directory so that python will use the module you just installed.

8 years ago No, I'm not. I don't understand what goes wrong....

8 years ago It might be a confusion between different versions of python I have on my system....
You could close the issue.....
thanks....

8 years ago Yes, that can cause confusions. That's why we recommend anaconda python. Or you need to create a virtual environment.

7 years ago I use anaconda3-4.3.0 on Ubuntu 16.04 and create a python2 virtual environment.
here is my build configuration
-- Uni10: The Universal Tensor Network Library
-- -- Version: 1.0.0 -- Generator: Unix Makefiles -- Build Target: Linux-x86_64 -- Installation Prefix: /home/xich/local/uni10 -- CXX Compiler: /usr/bin/c++ -- CXX Flags: -fPIC -std=c++11 -- BLAS and LAPACK Libraries: /home/xich/anaconda3/lib/liblapack.so;/home/xich/anaconda3/lib/libblas.so -- Build APPACK Support: YES -- - ARPACK Libraries: /home/xich/anaconda3/lib/libarpack.so -- Build HDF5 Support: NO -- Build Examples: YES -- Build Python Wrapper: YES -- - Python Excutable : /home/xich/anaconda3/envs/py2/bin/python -- - Python Headers : /home/xich/anaconda3/envs/py2/include/python2.7 -- - Python Library : /home/xich/anaconda3/envs/py2/lib/libpython2.7.so -- - Swig Version : 3.0.10 -- - Swig Directory : /home/xich/anaconda3/share/swig/3.0.10 -- Build CUDA Support: NO -- Build Documentation: NO
I build and install correctly uni10 library without any error. But when I run python egB1.py, I got
(py2) xich@xich:python$ python egB1.py
Traceback (most recent call last):
File "egB1.py", line 2, in
Any suggestions?

I'm wondering what is wrong?
