Greetings, @hemangjoshi37a! Looks like the problem occurs due to some version conflicts with external libraries (probably, seaborn). Unfortunately, it is not clear how to reproduce this. It would be useful if you provide more details of your environment:

• Which version of python do you use?
• Which version of Fedot are you trying to install? Are you install it via pip?
• Versions of requirements?
• Full version of the script that was run

You can provide your venv configuration or docker-image where it can be reproduced. Thank you!

Thank you for the details.

Python Version : 3.8.6 (64bit)

From the provided logs, it looks like the errors in your notebook are related to Python 3.9.

Also, the class names are similar to the GitHub master version, not the 0.3.1 from PyPI (for example "from fedot.core.pipelines.pipeline import Pipeline" was "from fedot.core.chains.chain import Chain" is 0.3.1)

So, can you check that kernel that is used to run the notebook?

[hemangjoshi37a]

@nicl-nno Thank you for the response sir.

I have set my kernel version to 3.8.6 (64bit) but the notebook keeps importing from python 3.9 libraries. I don't know why does that happen?

And I dont exactly remember whether I have installed Fedot from master branch or from pypi.

[hemangjoshi37a]

Actually it would be great to support python3.9 because I see that it is very well adopted version.

[hemangjoshi37a]

Also as you can see here that by installing Fedot from PyPI it gets stuck at "Building wheel for pandas (PEP517)"

[J3FALL]

Ok, thanks! Looks like some of the libraries are not well suitable for python 3.9 (pandas and SALib, for instance).

We will discuss it with the team and probably adapt fedot for python 3.9 soon.

[hemangjoshi37a]

Still cant install in python3.9. Hope to see the dependencies resolved soon.

[nicl-nno]

We refactored the requirements in the current master version to make it compatible Python 3.9. Is it works for you now? The release with this updates is coming soon.

[nicl-nno]

The support for 3.9 added.
