cannot import name 'Table' from 'perspective'

[wayjeeair]

Ran a 1 liner script on jupyterlab

from perspective import Table

[sc1f]

We don’t have a Mac build for conda - you’re most likely pulling in the Linux distribution (that’s just my assumption based on #1108)

What do your install logs look like when you try to install through conda? What does perspective.__dict__ show?

[wayjeeair]

Yup, I installed on a Mac. Didn't have an issue installing via pip install. However, when running via CLI, I ran into C++ binding issues mentioned in the issues opened. Attempted to skip through the binding issue by using jupyter lab.

Here is the install log on the re-installation of the python package. I guess there is no way around the binding issue even while using jupyterlab?

Yeah, if you hit the binding issue it means you won't be able to import anything except PerspectiveWidget, which you should then be able to run in "client mode" as described here.

If you run import perspective in Jupyterlab it'll give you the same error message as the one you saw in the CLI. We are in the process of distributing OSX wheels and fixing the conda build for Mac and Windows - what happens when you run pip install -v perspective-python? I can narrow down the issue from those logs and fix your build for now.

Sorry about the trouble installing!

[wayjeeair]

I had not much of an issue installing in the anaconda env. despite that, I am unable to import. hope my log would be helpful to you! would defo love to use the product in node, but im not too familiar with javascript. no worries, hope this works out!
