error when importing the bayesflow

[Shuwan-Wang]

Hi Stefan et al.,

I am so impressed by the bayesflow work. However, when I try to implement it myself, I got an error when importing the bayesflow.

I have tried with Pycharm/Anaconda, they gave me the same error message:

ValueError: Arg specs do not match: original=FullArgSpec(args=['input', 'dtype', 'name', 'layout'], varargs=None, varkw=None, defaults=(None, None, None), kwonlyargs=[], kwonlydefaults=None, annotations={}), new=FullArgSpec(args=['input', 'dtype', 'name'], varargs=None, varkw=None, defaults=(None, None), kwonlyargs=[], kwonlydefaults=None, annotations={}), fn=<function ones_like_v2 at 0x000002D9E1F41A80>

Do you know what happened and how to solve this?

Thank you so much!
Best regards,
Shuwan

Hi Shuwan, I have never seen such an error before. What system are you using (e.g., Python version, TensorFlow version, etc) and did you install bayesflow via pip?

Hi,

I am using the latest Python (3.11.5) and I never installed TensorFlow before installing Bayesflow. Yes, I installed the bayesflow via pip in the terminal.

Thanks!

It should have automatically been installed as part of the dependencies. Can you try with Python 3.10 following these instructions:

https://github.com/stefanradev93/BayesFlow/blob/master/INSTALL.rst

?

Also, do you have Windows or Linux/Mac?

[Shuwan-Wang]

Yes, I can reinstall Python 3.10, and I have Windows.

Let me know how this goes.

Hi,

I installed bayesflow via pip in Python 3.10.1, and it really seems downloaded all the packages and dependencies.

However, when I import bayesflow at the editor, it generates the following error:

I really don't know what happened here, could you take a look?

Thank you so much!
Best,
