Show examples in tensorflow datasets not working

问题

I want to load the tensorflow flowers dataset and visualize it using tfds.show_examples.

import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt
import tensorflow_hub as hub
import tensorflow_datasets as tfds   
from tensorflow.keras import layers

import logging
logger = tf.get_logger()
logger.setLevel(logging.ERROR)

(train_examples, validation_examples), info = tfds.load(
    'tf_flowers', 
    with_info=True, 
    as_supervised=True, 
    split=['train[:70%]', 'train[70%:]'],
)

fig = tfds.show_examples(train_examples, info)

When I run my code, instead of seeing images, I get an error message:

AttributeError                            Traceback (most recent call last)

<ipython-input-13-dcdedbcd800d> in <module>()
      6 )
      7 
----> 8 fig = tfds.show_examples(train_examples, info)

/usr/local/lib/python3.6/dist-packages/tensorflow_datasets/core/visualization.py in show_examples(ds_info, ds, rows, cols, plot_scale, image_key)
     68     # Infer the image and label keys
     69     image_keys = [
---> 70         k for k, feature in ds_info.features.items()
     71         if isinstance(feature, features_lib.Image)
     72     ]

AttributeError: 'DatasetV1Adapter' object has no attribute 'features'

Why is this not working?

回答1:

I had the same problem using Colab. Try this

pip install --upgrade tensorflow-datasets

and restart the kernel
