How do I How do I run the.py file in python/examples/？

[tanghao123th]

Excuse me,when I run the.py file in python/examples/,I got a fail.
For example,I type the python contraction.py command to run contraction.py.
The result is as follows:
A1 shape: (2, 3)
B1 shape: (3, 4)
Traceback (most recent call last):
File "contraction.py", line 37, in
test_exatn()
File "contraction.py", line 18, in test_exatn
exatn.createTensor('C1', [2, 4], 0.0)
AttributeError: module 'exatn' has no attribute 'createTensor'

What should I do?

I am not sure, I can run it fine on my laptop with python3:

python3 ./contraction.py
A1 shape: (2, 3)
B1 shape: (3, 4)
C1 shape: (2, 4)
D1 shape: (2, 4)
NumPy result c1 = a1 * b1:
[[1. 0. 3. 0.]
[0. 2. 0. 4.]]
ExaTN result c1 = a1 * b1:
[[1. 0. 3. 0.]
[0. 2. 0. 4.]]

Maybe, check you build configuration and make sure you set
"export PYTHONPATH=$PYTHONPATH:$HOME/.exatn"
and use Python3?
