cannot save MLP_model

[beinathan]

When I try to use pickle to save mlp_model，it has the following error:
AttributeError: Can't pickle local object 'MLP.init..'
I also has tried dill, but still not, so how to solve it?

Hello. This is because there's a lambda function in the MLP class. I'll send a fix which will be available in the next release. Thanks for notifying us!

Hey Max, I too am facing the issue, I have installed the development version, still not working. Any fix?

[MaxHalford]

Hey! Can you share some details about your setup? Your Python version, numpy, etc.? I'm going to dive into this issue before making the next release.

setup.txt
Hey Max! the file contains all the packages installed with River in my environment. Fyi, I had to design the environment carefully. I require GPFlow and River in the same environment and I have noticed that slight tweak here and there breaks the environment and River fails to load with some error with Numpy. Hoping to get a fix soon.

Okay, thanks for your answer.

You can install the development version if you want :)
