py_call_impl nevergrad error: got an unexpected keyword argument 'lower'

[cervuspc]

Hi guys, I tried to run the demo project.
No errors in reticulate and nevergrad installation, but when I run the Step 3 and the first trial is going to start...I receive the following error:
"Error in py_call_impl(callable, dots$args, dots$keywords) :
TypeError: init() got an unexpected keyword argument 'lower'"

Thanks in advance

I've seen this error before that's related to older Nevergrad version. Can you reinstall nevergrad and retry?

[cervuspc]

Hi, thank you for your replay. I have updated all the packages but the problem still remains.
nevergrad --> 0.4.3.post8
python --> 3.8.12
let me know.
thanks

It's tricky because I can't reproduce your issue. I found this issue that's related to reticulate version. rstudio/reticulate#831. I have reticulate_1.22. Which one are you using?

[cervuspc]

I'm using reticulate 1.22 as well but I have always the same error :(

[gufengzhou]

Hm this is really strange. The "lower" argument is when setting up nevergrad's hyperparameter bounds in ng$p$Array(shape = my_tuple, lower = 0., upper = 1.), a new argument introduced in nevergrad --> 0.4.3.post8. I would assume it's still because of Nevergrad installation issue. A dumb idea is to remove and reinstall python etc again, as specified in the last comment in this thread. It's really difficult to debug without reproducibility

feel free to reopen if necessary

I have run the model in a good way for the first 2 trials, one with the demo and one with my own data, while i have encounter the same issue with py_call_impl, unexpected arguement 'lower', I have tried remotes::install_github("rstudio/reticulate"), but it doesn't work, seems I need to reinstall from the very beginning.

Hi, what’s your version of Robyn then? My version of Robyn was 3.5.x previously, and currently the latest version is 3.6.3. I thought it might be the Robyn version issue to pop the error warning, so I tried to remove previous Robyn and reinstall, then I found the my rlang should also be updated to 1.0.2. After rlang to 1.0.2, Robyn to 3.6.3, and I also remove packages reticulate and get it reinstalled, now, Robyn works.

@laresbernardo I think i've being using the latest version of Robyn and reticulate. Nevergrad also seems to be successfully installed. However i still have this issue as i reported here #691. Any suggestions? Thank you.
