Error in the lttbc=0.2.0 dependency. Blocks the installation in openshift

[thanosam]

In my app, when I add the plotly-resampler in my requirements file and I try to deploy it in openshift I receive the following error:

It seems that in setup.py file of the lttbc==0.2.0 is imported the numpy in line 7, something that changed in lttbc==0.2.1. Why in your dependencies exists lttbc==0.2.0 and not lttbc>0.2.0?

Hi @thanosam

In commit 5ed847b @jonasvdd fixated the version on 0.2.0 (perhaps he can explain why?)

However, in PR #103 we added an adapted C implementation of the LTTB algorithm in this repository. As such the lttbc dependency is dropped now.
We haven't made a new release yet, but you can try install the pre-release? pip install plotly-resampler==0.8.0rc5

Cheers,
Jeroen

Hi @thanosam, can you confirm that installing the pre-release resolves the issue?

[thanosam]

I didn't install the prerelease yet. Currently I solved it by forcing the installation of numpy in the setup file.

Hi @thanosam,

Have you found time to install the pre-release? (currently the latest is pip install plotly-resampler==0.8.0rc12)

[thanosam]

Hello,

I tried the 0.8.0rc12 and it seems that it works. But since it's prerelease, I install back the 7.2.2 with the setup file solution and I work with this version.

[jonasvdd]

okay, as it seems resolved, I will close this issue for now!
