kandi X-RAY | twitter-sentiment-cnn Summary
The network implemented in this script is a single layer CNN structured as follows: - Embedding layer: takes as input the tweets (as strings) and maps each word to an n-dimensional space so that it is represented as a sparse vector (see [word2vec] - Convolution layers: a set of parallel 1D convolutional layers with the given filter sizes and 128 output channels. A filter’s size is the number of embedded words that the filter covers. - Pooling layers: a set of pooling layers associated to each of the convolutional layers. - Concat layer: concatenates the output of the different pooling layers into a single tensor. - Dropout layer: performs neuron dropout (some neurons are randomly not considered during training). - Output layer: fully connected layer with a softmax activation function to perform classification.

QUESTION
I'm trying to run a CNN model for sentiment analysis and I get an error that shows:
...File "twitter-sentiment-cnn.py", line 292, in test_batches = list(batch_iter(zip(x_test, y_test), FLAGS.batch_size, 1))
File "/home/sanaa/Sentimental/Cnn/twitter-sentiment-cnn/data_helpers.py", line 179, in batch_iter data_size = len(data1) TypeError: len() of unsized object
ANSWER
Answered 2018-Apr-20 at 18:35In python3, len
cannot be used with iterators, and zip
returns an a zip object, which is an iterator. My guess is that np.array() preserves the iterator. If you need the length, you may need to apply list()
, though that may have scalability consequences.
