Convert list of tuples to tensorflow dataset (tf.data.Dataset)

Question

Data from kaggle Natural Language Processing with Disaster Tweets

ds_train

>>>[("Already expecting to be inundated w/ articles about trad authors' pay plummeting by early next year but if this is true it'll be far worse",
  0)
 ('@blazerfan not everyone can see ignoranceshe is Latinoand that is All she can ever benothing morebut an attack dog 4 a hate group GOP',

I want to convert it to tensorflow datasets.
I tried tf.data.Dataset.from_tensor_slices(ds_train) but got error

ValueError: Can’t convert Python sequence with mixed types to Tensor.

Answer 1

One option would be to split the tuple:

import tensorflow as tf

data = [("Already expecting to be inundated w/ articles about trad authors' pay plummeting by early next year but if this is true it'll be far worse", 0), ('@blazerfan not everyone can see ignoranceshe is Latinoand that is All she can ever benothing morebut an attack dog 4 a hate group GOP', 0)]
x, y = zip(*data)
dataset = tf.data.Dataset.from_tensor_slices((list(x), list(y)))

With a dataframe:

dataset = tf.data.Dataset.from_tensor_slices((df['text'], df['target']))
