reticulate

问题 I'm trying to work with the reticulate library in R. I used the "functions.py" example to test it out: # functions.py file def add(x, y): return x + y In R studio (Version 3.5.2), this is what I have: library(reticulate) source_python('functions.py') However, this returns an error: Error in py_set_attr_impl(x, name, value) : Evaluation error: ModuleNotFoundError: No module named 'rpytools'. So I'm stuck here. If it helps, I'll also share that my Python is 64-bit and version 3.6.5. Anyone know

问题 Maybe I'm missing something, but if the following code is the content of my Rmd file ```{r} library(reticulate) use_virtualenv("r-reticulate") py_available(TRUE) ``` ```{python} a = 7 print(a) ``` ```{r} py$a ``` when I Knit the file, the output for the last chunk is 7 (as expected). On the other hand, clicking the run all button in Rstudio (or running chunks one by one), results on NULL for the last chunk. Comparing with the R notebook example it seems like assigning something to flights in

问题 I'm venturing into using Reticulate in R and having trouble installing a package, specifically psycopg2 but I've also tried installing twisted with the same result. after I load reticulate in R I double check to make sure my package is installed: > conda_install(envname = "r-reticulate", packages="psycopg2") Solving environment: ...working... done # All requested packages already installed. Looks good. So I set my condaenv to r-reticulate just to be double sure. The docs say I should not have

问题 I'm trying to use the Reticulate package to use Python through R. I successfully connected Reticulate to Python 3.6 with Sys.setenv(RETICULATE_PYTHON = "/usr/local/bin/python3") . Then after noticing that my Python 3.6 didn't have Numpy, I used entered pip3 install numpy into the command line and installed it. Now, I am having the following problem with Reticulate when I call py_config() : py_config() Error in py_run_string_impl(paste0("import sys; sys.path.append('", system.file("python", :

问题 I am having trouble getting the reticulate package in R to work. It cannot find the shared LIBPYTHON file it needs, no matter which version of Python I have loaded via module load , or which version I tell reticulate to use, directly within R. I'm working on the universty's cluster, which has several versions of Python installed and are loaded via modules. Thank you for your help. a) Using version 2.7.9 (default version from module load CBC ) : > reticulate::py_discover_config() python: /opt
