Plot(model) does not see graphviz in R on Windows #4

Hi! I am triyng to reproduce in R some examples from Chapter 7. (Win 10x64, 22H2) Calling plot(model) after Listing 7.11 falls with error: "See ?keras::plot.keras.engine.training.Model for instructions on how to install graphviz and pydot Error in plot(model) : ImportError: You must install pydot (pip install pydot) and install graphviz (see instructions at https://graphviz.gitlab.io/download/) for plot_model to work." But I have installed both pydot and graphviz - I did it a lot of times in different ways. Currently it looks like this:

reticulate::py_list_packages(envname = "r-reticulate", type = "conda" ) ................... graphviz 7.1.0 graphviz=7.1.0 conda-forge ................... pydot 1.4.2 pydot=1.4.2 conda-forge

> reticulate::py_config() python: C:/Users/UserName/miniconda3/envs/r-reticulate/python.exe libpython: C:/Users/UserName/miniconda3/envs/r-reticulate/python38.dll pythonhome: C:/Users/UserName/miniconda3/envs/r-reticulate version: 3.8.16 | packaged by conda-forge | (default, Feb 1 2023, 15:53:35) [MSC v.1929 64 bit (AMD64)] Architecture: 64bit numpy: C:/Users/UserName/miniconda3/envs/r-reticulate/Lib/site-packages/numpy numpy_version: 1.24.2

After many hours of searching on the internet I still can't manage to fix this error. So I would appreciate you help me to solve it.

Hi, thanks for reporting. I responded to the issue here https://github.com/rstudio/keras/issues/1337, which is I think the same issue.

As a workaround until this is fixed, you can run your plot() calls outside the RStudio IDE (not ideal, I know).
