Read Data Command - Preview actual rows from a dataset.
Functions
tuiml read-data [OPTIONS]
Preview actual rows from a dataset.
Returns real rows as a list of records, so you can eyeball the values, column names and encodings without loading the file yourself. Rows can be taken from the head or the tail, drawn as a random sample, or picked out by index, and --columns narrows the output down to a few fields. The label column comes along unless you pass --no-include-target.
Preview the first rows of a built-in dataset:
bash
$ tuiml read-data --data irisDraw a random sample of five rows:
bash
$ tuiml read-data --data data.csv --mode sample --n-rows 5Pull out specific rows by index:
bash
$ tuiml read-data --data data.csv --mode indices --indices '[0,7]'Options
