Execute code that traverses a dataset

Execute code that traverses a dataset

with_dataset(expr)

Arguments

Details

When a dataset iterator reaches the end, an out of range runtime error will occur. You can catch and ignore the error when it occurs by wrapping your iteration code in a call to with_dataset() (see the example below for an illustration).

Examples

# NOT RUN {
library(tfdatasets)
dataset <- text_line_dataset("mtcars.csv", record_spec = mtcars_spec) %>%
  dataset_prepare(x = c(mpg, disp), y = cyl) %>%
  dataset_batch(128) %>%
  dataset_repeat(10)

batch <- next_batch(dataset)

with_dataset({
  while(TRUE) {
    # use batch$x and batch$y tensors
  }
})
# }
