Fehler beim Ausführen von zfit unter Ubuntu 22.04 mit Python 3.10.12 und TensorFlow 2.18.0 ⇐ Python

[Guest]

Ich versuche, zfit auf meinem Ubuntu 22.04-Laptop auszuführen. Ich habe es so installiert:

Code: Select all

python -m venv venv
source venv/bin/activate
pip install zfit

Ich habe diesen Code ausgeführt (von https://github.com/zfit/zfit):

Code: Select all

import zfit
import numpy as np

obs = zfit.Space('x', -10, 10)

# create the model
mu    = zfit.Parameter("mu"   , 2.4, -1, 5)
sigma = zfit.Parameter("sigma", 1.3,  0, 5)
gauss = zfit.pdf.Gauss(obs=obs, mu=mu, sigma=sigma)

# load the data
data_np = np.random.normal(size=10000)
data = zfit.Data(obs=obs, data=data_np)
# or sample from model
data = gauss.sample()

und ich habe diesen Fehler:

Code: Select all

Ich habe das Gleiche mit Python 3.11 auf demselben System erlebt.
