@mariacarmina @calina-c Tagging you here because I do not have the permissions yet to assign this issue directly to you.

[mariacarmina]

I don't think is due to ocean-lib and it seems to come from your python setup. I have searched the problem a bit and found an answer here. It seems that mixes Python 2 with Python 3.

[graceful-coder]

As a user, I shouldn't have to update my main_wrapper.c file on my machine to run ocean-lib properly. Here is a screen recording to show my installation process from the readmes and the import failure.

[mariacarmina]

There is a problem related on how did you manage to install python on your machine. It's a Python version issue that you have encountered, not an ocean-lib issue.

[graceful-coder]

So what you're saying is that I can't run Ocean-lib with Python 3.9.12 as installed by Anaconda?

[mariacarmina]

Anaconda is not yet fully supported, check in install.md https://github.com/oceanprotocol/ocean.py/blob/main/READMEs/install.md#install-oceanpy-library. The comment right above python3 -m venv venv. So if the python is installed by Anaconda, maybe that's why you are facing these issues.

[graceful-coder]

It shouldn't be a problem with Python 3.9.12 being installed by Anaconda... That comment refers to not being able to use a conda virtual environment. Either way, I will go through uninstalling python entirely on my system and install an old version of python to try to get this working. Will report back.

[graceful-coder]

Resolved by installing Python 3.10.4.

Takeaway: Cannot use either conda virtual environment, nor even a Python install by Anaconda with ocean-lib.

I got the following import error message after setting up my virtual enviornment and installing ocean-lib. I am using Windows.

ImportError: cannot import name 'Accounts' from partially initialized module 'brownie.network.account' (most likely due to a circular import) (C:\Users\Chris\oceanpy\venv\lib\site-packages\brownie\network\account.py)

[mariacarmina]

@calina-c has a PR on anaconda project and this issue seems related to #1203. I'll also assign @calina-c on this one since she had som workaround on this topic.

[calina-c]

@graceful-coder it seems from your comment the issue was solved?
@ChristianCasazza it looks like your issue is unrelated to Anaconda. Could we create a separate issue for your last comment? I'll help you debug it but let's set clear scopes.

Closing as discussed on Slack with Christian.
