Fail to import multistack module

[zwdiscover]

Hi, I just realized this was a python compatibility problem. If I created a new conda environment with an older Python version 3.6.13, the problem solved. I think this multistack module is not compatible with the newest Python version, at least for the case of v3.9.7.

Hello @zwdiscover,

The subpackage bigfish.multistack is new in big-fish v0.6.0, so I think you just needed to update you big-fish version. On my side it's working fine with python 3.9.7.

In your previous environment, just run:

pip install --upgrade big-fish

I just tried your suggestion but still failed. The version for big-fish was still v0.3.0, so weird. Only my new conda environment with Python 3.6.13 was installed with big-fish v0.6.0 by default.

[Henley13]

So the notebook is working with big-fish >= 0.6.0, right?

I do not know why you still have big-fish 0.3.0 in your original environment. What command did you run? What was the error message if any?

[zwdiscover]

Yes, the notebook is working with big-fish 0.6.0.
I always used "pip install big-fish" to install bigfish under different conda environment. Under anaconda/python v3.6.13, the default installing version for bigfish is v0.6.0. However, under anaconda/python v3.9.7 and anaconda/python v3.10.0, the default installing version for bigfish is v0.3.0. I tried different conda environment on two different mac computers: mac mini and macbook air. The same problem existed. Looks very strange to me.

[Henley13]

So could you try pip install --upgrade big-fish in these environment? Then you can check you big-fish version with pip list.

[zwdiscover]

I ran the upgrade command as well. But after this, the version for big-fish was still v0.3.0 under python v3.9.7 and v3.10.0.

Ok I reproduced the error. Indeed, big-fish v0.6.0 is installing with python 6 and 7, but not with the more recent versions. The problem comes from the pinning dependencies in big-fish (scikit-learn==0.21.0 specifically). In the next version, unpinning dependencies and a more recent version of scikit-learn will solve the problem. Until then you should downgrade your python version unfortunately. I will try to push big-fish 0.6.1 soon.

Thanks for raising the issue!

Hi @zwdiscover, I just released 0.6.1. Normally if you set up a new environment with python 3.8+, you should be able to install big-fish 0.6.1.

Thanks for letting me know. I uninstalled previous version in my current environment and reinstalled it. It is running in the newest version 0.6.1 now. I further tested two of the notebooks using the multistack module. Working well now.

Take care, I also updated the notebook repository.
