MQT predictor installation

[tanmay0550]

Facing the issue in ML notebook run

cannot import name '_TEMP_BIT_NAME' from 'pytket._tket.circuit

Hey 👋🏻

That's an underlying TKET error that came up in one of the recent versions. Should be resolved by updating your TKET version via

pip install -U pytket

[burgholzer]

My bad. I only vaguely remembered the cause for that issue. You have to update both the pytket package and the pytket-qiskit package.

pip install -U pytket pytket-qiskit

See CQCL/tket#1023 for more details.

I tried but it's still the same issue

can you mention the dependencies that should be followed from python version to mqt.predictor mqt.bench

[tanmay0550]

Issue is mqt-bench 0.4.4 requires pytket-qiskit<0.40.0,>=0.34.0, but you have pytket-qiskit 0.44.0 which is incompatible.

I can reproduce your error with the following steps

git clone https://github.com/cda-tum/mqt-predictor
cd mqt-predictor
python3 -m venv .venv
. .venv/bin/activate
pip install -U pip setuptools wheel
pip install .

I traced back the issue to the following package version issue:
The above command install pytket-qiskit 0.39.0.
That package declares a dependency on pytket~=0.15.
Due to the way dependencies work in Python, this installs pytket-1.20.1, when in reality the TKET developers most likely intended to write pytket~=0.15.0, which would have led to pytket-1.15.0 being installed.
To resolve the problems you are seeing, you can simply downgrade to a compatible pytket version via

pip uninstall pytket
pip install pytket~=1.15.0

At least on my setup, that resolved the issue.

Note that we are currently in the process of a substantial rewrite in #130 that also updates all underlying dependencies and ensures that the predictor is compatible with the recent versions of TKET and Qiskit.

FYI: I also opened CQCL/pytket-qiskit#182 to clarify this with the TKET developers

thanks atleast error now changed to cannot import name 'qiskit_helper' from 'mqt.bench.utils

[burgholzer]

OK. that one I cannot reproduce. Given the above setup, I can run both the ml/evaluation.ipynb and the ml/runtime_comparison.ipynb notebooks without errors.
Make sure that you haven't messed around with the package versions too much. In particular, the current mqt-predictor version is compatible with mqt-bench==0.4.4.

[tanmay0550]

It worked, thanks lukas sorry for disturbing you so much

[burgholzer]

No worries! Glad that I could help! 👍🏼
Don't hesitate to open op another discussion if further issues should pop up!

Finding difficulty in running ML notebook

predictor.plot_eval_histogram(res, filename="RandomForestClassifier", color=color1)

Predictor.plot_eval_histogram() got an unexpected keyword argument 'color'

any reasons?

Hi,

unfortunately I cannot reproduce the error you got. What version of mqt.predictor is installed in your environment?
