Well, otherwise, one can simply validate if `var()` is numeric: ``` library(tidyverse) datasetInput

This is the last one, I promise! After reading [this](https://shiny.rstudio.com/articles/req.html), it seems the easiest way to do it is to validate the `input$var` in `reactive()` via `req()`: ``` library(tidyverse) datasetInput

Not sure though if I'd better ask this on Stackoverflow 🙂

I also have tried: * Previous versions of `runtimeVersion` (1.15) and Python (2.7) * Use `install_tensorflow()` inside the script

Oh, I faced exactly the same issue today. Is there any other workaround? Is there a way to access the enclosing "parent" environment from `f1()`? Here is my tiny reprex:...

Thanks for your replies and approaches. I'm rather fond of the one on the SO. Do you think it's an ok-ish idea to develop a package using this approach?

I prefer it because of the syntax. I'm mimicking a Python API package, which has nested attributes/methods. E.g., I'm trying to represent a Python method call `object.level1.level2.method()` with `object$level1$level2$method()`. Of...

Btw, if I'm not mistaken, Reference Classes have the same issue, no no-go there as well.

Will do. One more thing, I noticed that with different FPS I got different resolutions. I will try to prepare another reproducible example(s) and will get back with more details.

Here are my observations: - `CAMERA_FORWARD`: - `LOW_RESOLUTION`: (478, 648, 3) - `HIGHT_RESOLUTION`: (720, 960, 3) - `CAMERA_DOWNWARD`: (720, 320, 3) Probably I should ask this in the other issue,...
