Project Robyn

Describe issue

Robyn tells me Nevergrad is not installed, even though it should be as I've run the code before without issues (see screenshot).

I see that Robyn runs reticulate's py_module_available() under the hood to produce this error, which is basically reticulate's import() function with an error handler, so I ran this code manually which produced the following error:

Is it possible that this error is then caused by the use of a deprecated NumPy feature?

Environment & Robyn version

Robyn version: 3.11.0
R version: 4.4.0

I got the same issue as well, but 2 weeks back it was working fine for me as well. Any luck solving it ?

This error needs an update from the Nevergrad's side. I'll ping them and keep you updated.

Seeing the same error. Tried to install an older version of nevergrad, still no luck.

@gufengzhou I'm no longer getting the same error, but a new one:

Will this require an update on Robyn's end?

gufengzhou commented

Have you updated /reinstalled nevergrad? If yes please also restart R and try.

After the above, If this still occurs, an user here has solved it by updating the R version. See #1006

Would you please let me know if you needed to update R or not?
If yes, which R versions did you have before/after?

I did need to update, yes. I updated from 4.4.0 to 4.4.1
