Hi ! i try to run this dataset but can not https://skeydan.github.io/Deep-Learning-and-Scientific-Computing-with-R-torch/audio_classification.html

library(torch)
 library(torchaudio)
 library(luz)

 ds <- speechcommand_dataset(
   root = "~/.torch-datasets", 
   url = "speech_commands_v0.01",
   download = TRUE
 )

Error in if (!tools::md5sum(destfile) == checksum) runtime_error(glue::glue("MD5 sums are not identical for file: {destfile}.")) : 
  missing value where TRUE/FALSE needed
In addition: Warning messages:
1: In utils::download.file(url = url, destfile = destfile) :
  URL https://storage.googleapis.com/download.tensorflow.org/data/speech_commands_v0.01.tar.gz: cannot open destfile '~/.torch-datasets/speech_commands_v0.01.tar.gz', reason 'No such file or directory'
2: In utils::download.file(url = url, destfile = destfile) :

Hi @mytarmail

Thanks for reporting, this is a bug in our implementation which fails if the root directory doesn't exist. A workaround is to, create the directory first, and then pass to the root argument.

library(torch)
library(torchaudio)
library(luz)

dir <- fs::dir_create("~/torch-datasets")
ds <- speechcommand_dataset(
  root = dir, 
  url = "speech_commands_v0.01",
  download = TRUE
)
