Cannot install keras on Mac M1

[harshvardhaniimi]

I can't seem to be able to install keras in my MacBook Air (M1, 2020). I'm following the directions in this tutorial.

When I run the following commands, they run well.

install.packages(keras)
library(keras)
dataset_mnist()

Then, I restart my R session. Following that, I run

keras::install_keras(method = "conda",
                     conda = "~/Library/r-miniconda-arm64")

It gives me following error:

Error: Tensorflow installation failed (no conda binary found)
Install Miniconda by running `reticulate::install_miniconda()`before installing Tensorflow.

I specified conda = "~/Library/r-miniconda-arm64 because I know I have a miniconda there. How? Because when I try installing Miniconda, I get the following error.

Error: Miniconda is already installed at path "~/Library/r-miniconda-arm64".
- Use `reticulate::install_miniconda(force = TRUE)` to overwrite the previous installation.

I tried forcing a fresh installation but it gave me the following error.

ERROR   Could not solve for environment specs
Error: miniconda installation failed [exit code 1]

I'm aware of the previous issues raised in #434 and #691 but they did not help my case. Can anyone take a look please? Thanks!
