現在、実験で GMM を使用しようとしています。しかし、次の問題があります。私はエラーについてかなり混乱しています。
import tensorflow as tf
class GMMDataLoader:
def __init__(self, points, batch_size):
self.points = points
self.batch_size = batch_size
num_points = points.shape[0]
self.num_points = num_points
dim = points.shape[1]
self.count = 0
#self.x = tf.constant(self.points)
print ('Loaded in a total of %d points, the dimension is %d'%(num_points, dim))
def next_batch(self, batch_size=128):
self.count += 1
count = self.count + 1
print ('batch [%d]'%count)
num_points = self.num_points
x = tf.constant(self.points)
indices = tf.random_uniform(tf.constant([batch_size]),
minval=0, maxval=num_points-1,
dtype=tf.int32,
seed=10)
return tf.gather(x, indices), None
import numpy as np
x = np.random.random((10000, 2048)).astype('float32')
loader = GMMDataLoader(x, 128)
gmm_model = tf.contrib.factorization.GMM(initial_clusters='random', num_clusters=100, random_seed=666)
gmm_model.fit(input_fn=loader.next_batch)
このコードを実行すると、次のエラーが発生します。
Loaded in a total of 10000 points, the dimension is 2048
