spyder: KeyError('pandas._libs.interval') while opening a dataframe in variable explorer in dmg version of spyder

There’s a workaround. Please go to pull request https://github.com/spyder-ide/spyder/pull/14600, click on View details, then the Details link to the right of macOS App Bundle (Full), then Artifacts (to the right):

and finally click on Spyder.dmg on the menu that appears there.

That will give you an installer with our latest fixes in our stable branch (i.e. everything that will be part of 4.2.2, including our fix for Pandas). However, please be aware that it could contain other bugs or problems because it’s still a work in progress.

The only question is wouldn’t it be better to provide us a dmg version for Spyder 4.2.2.dev instead of Spyder 4.3.0.dev0? I’m not sure whether it’s possible, I just think it would be safer considering the probable bugs!

Good thinking. However, that correspond to the way we name development versions. We don’t name bugfix releases (i.e. 4.2.2dev0), just minor ones (i.e. 4.3.0dev0).

I understand that’s a bit odd (specially because there’s not going to be a 4.3.0 release at the end), but we decided to do that years ago for all projects we maintain, so now it’s kind of hard for us to change it.

Got you! If it’s only a naming thing, it won’t be an issue. Again Thanks!

Hi @mhdmyz, thanks for reporting this issue, this was fixed on https://github.com/spyder-ide/spyder/pull/14545, which is going to available on the next Spyder release, v4.2.2. Until the next release is available, there is nothing much we can do at this moment. Thanks for you patience
