Cannot access R variables from Python when running from command line

[jbentleyEG]

The following code works from RStudio but not when using R from the command line and calling 'render' on an rMarkdown notebook.

```{r python}
b <- 2
```

```{python}
print(r.b)
```

When executing from RStudio it prints '2' as expected, but if I run R from the command line it fails with

Error in py_call_impl(callable, dots$args, dots$keywords) :
RuntimeError: Evaluation error: object 'b' not found.

Detailed traceback:
File "", line 1, in
File "/Library/Frameworks/R.framework/Versions/3.6/Resources/library/reticulate/python/rpytools/call.py", line 21, in python_function
raise RuntimeError(res[kErrorKey])

Reticulate v1.16 works as expected, but versions 1.17 and 1.18 are broken. My guess is that it is related to this commit: fcd969e

Do you see this with the development version of reticulate as well? remotes::install_github("rstudio/reticulate")

I just tested it, it does appear to be fixed in the current dev version (1.18-9000).

Thank you!

Great, thanks! I'll try to get a new version of reticulate published to CRAN soon.

[jbentleyEG]

Awesome, thanks for the super quick turnaround

reticulate 1.19 is now on CRAN.
