I am building a hybrid CNN-RNN architecture to make a predictive model. I have used Keras implementation with TensorFlow. But I keep getting this error -
File "try.py", line 56, in <module>
model.fit(data, labels, epochs=10, batch_size=32)

ValueError: setting an array element with a sequence.
I am attaching my code here
import gensim
from gensim.models import word2vec
documents = ["Human machine interface for lab abc computer applications",
"A survey of user opinion of computer system response time",
"The EPS user interface management system",
"System and human system engineering testing of EPS",
"Relation of user perceived response time to error measurement"]
sentences = [[word for word in document.lower().split()] for document in documents]
word_model = gensim.models.word2vec.Word2Vec(sentences, size=200, min_count = 1, window = 5)
word_vectors = word_model.wv
data = np.array(word_vectors, ndmin = 2, dtype = object)
labels = np.array([0.214285714286], ndmin = 2 , dtype = object) #A Normalised Class Label Name
The data variable gives error It is supposed to be a numpy array but at its essence is still word vector sequence
converted the wv word vectors into a numpy matrix that is suitable for insertion into Keras model
