b2's Issues

Issues with launching B2

Please keep in mind I'm a complete beginner so this problem might be caused by something on my end.

I tried running B2 on Linux (Ubuntu 20.04 LTS), Python 3.8.

I was told to open and test out the notebooks, so I launched b2-ext on jupyter and opened the B2 folder. Then when I tried to open and run "Untitled.ipynb" I kept getting errors when importing B2 and midas. It kept saying "Import Error: cannot import name "Midas" from "midas"."Import Error: cannot import name "B2" from b2. I also tried typing in "Import b2" and running it. For this is got "ModuleNotFoundError: No module named "Data Science"."

Also, can you please give me something like a short beginner's guide on a proper way to actually run b2? I read all the instructions on github but I can't understand most of it since I'm so new. I would really appreciate it.

Sorry for the inconvenience.

brittle name handing with code synthesis

If a column name starts with a number, e.g., 10age_group, then the current code generates a python variable starting with 10, which is bad.

Issues about dashboard pane

I tried it on py3.7 in anaconda.
I also had installed b2-ext and datascience.
I can run it on jupyter notebook but I can't see the resizable dashboard pane...
Can you please tell me what should I do?

better data frame backends

Currently B2 uses https://github.com/data-8/datascience, which was chosen for its simple API, convenient for code generation. However it's very slow. It should be easy to swap out the execution with something like pandas, modin, and/or ibis.

B2 not loading because of a missing "midas" -> "b2" rename

After I ran...

pip3 install b2-ext

Somehow the nb extension config still produced a file with the name "midas" in it.

$ cat /Library/Frameworks/Python.framework/Versions/3.10/etc/jupyter/nbconfig/notebook.d/b2.json
{
  "load_extensions": {
    "midas/index": true
  }
}

B2 wouldn't load. But when I manually changed "midas" to "b2" in the file above, it worked.

I'd make a PR to fix this, but, despite searching for "midas" in the B2 source, I don't know where it went wrong!
