Hi! To me it looks like the pip-installed version is running. Have you tried upgrading that to the newest version as well? If so, please make sure you have enough credits on your quantum experience account.

I tried it again, installing both from source and pip, and still get the
same problem. Unfortunately
I don’t have much time to spend on this now because I think it is really
interesting.
Anyhow, here is what happens. First uninstall and delete previous versions.
Then
pip install projectq

Here’s the script:

eng = MainEngine()
q1 = eng.allocate_qubit()
H | q1

print("Measured: {}".format(int(q1)))
python3 projectq_test.py
gives

Measured: 0
Seems fine. Now try
eng = MainEngine(IBMBackend())
q1 = eng.allocate_qubit()
H | q1
Measure | q1
eng.flush()
print("Measured: {}".format(int(q1)))
python3 projectq_test.py

Thank you for trying again!
It seems that you installed the new version of ProjectQ for python2.7, but you're running your script using python3.6. Please, try executing
python2.7 projectq_test.py
instead or reinstalling using pip3 instead of pip.
Also, you can check that you have the newest version of ProjectQ (0.1.3) as follows:
import projectq
projectq.__version__
from projectq.
