tflearn：model.fitのValueError

私はTFLearnを初めて使用しており、簡単なCNNを作成しようとしています。ここに私のコードは次のとおりです。tflearn：model.fitのValueError

import tensorflow as tf 
import tflearn 
from tflearn.layers.core import input_data, fully_connected, dropout 
from tflearn.layers.conv import conv_2d, max_pool_2d 
from tflearn.data_utils import image_dirs_to_samples, to_categorical 
from tflearn.layers.estimator import regression 


if __name__ == '__main__': 

    NUM_CATEGORIES = 5 

    X, Y = image_dirs_to_samples('./flower_photos_100') 
    Y = to_categorical(Y, NUM_CATEGORIES) 

    net = input_data(shape=[None, 299, 299, 3]) 

    net = conv_2d(net, 32, 3, activation='relu', name='conv_0') 
    net = max_pool_2d(net, 2, name='max_pool_0') 
    net = dropout(net, 0.75, name='dropout_0') 

    for i in range(4): 
     net = conv_2d(net, 64, 3, activation='relu', name='conv_{}'.format(i)) 
     net = max_pool_2d(net, 2, name='max_pool_{}'.format(i)) 
     net = dropout(net, 0.5, name='dropout_{}'.format(i)) 

    net = fully_connected(net, 512, activation='relu') 
    net = dropout(net, 0.5, name='dropout_fc') 
    softmax = fully_connected(net, NUM_CATEGORIES, activation='softmax') 

    rgrs = regression(softmax, optimizer='adam', 
          loss='categorical_crossentropy', 
          learning_rate=0.001) 

    model = tflearn.DNN(rgrs, 
         checkpoint_path='rs_ckpt', 
         max_checkpoints=3) 

    model.fit(X, Y, 
      n_epoch=10, 
      validation_set=0.1, 
      shuffle=True, 
      snapshot_step=100, 
      show_metric=True, 
      batch_size=64, 
      run_id='rs')

私は、次のエラーを取得しています：

Traceback (most recent call last): 
    File "rs.py", line 46, in <module> 
    run_id='rs') 
    File "/usr/local/lib/python2.7/site-packages/tflearn/models/dnn.py", line 188, in fit 
    run_id=run_id) 
    File "/usr/local/lib/python2.7/site-packages/tflearn/helpers/trainer.py", line 277, in fit 
    show_metric) 
    File "/usr/local/lib/python2.7/site-packages/tflearn/helpers/trainer.py", line 684, in _train 
    feed_batch)

    run_metadata_ptr) 
    File "/usr/local/lib/python2.7/site-packages/tensorflow/python/client/session.py", line 888, in _run 
    np_val = np.asarray(subfeed_val, dtype=subfeed_dtype) 
    File "/usr/local/lib/python2.7/site-packages/numpy/core/numeric.py", line 482, in asarray 
    return array(a, dtype, copy=False, order=order) 
ValueError: setting an array element with a sequence.

私はそれがXの形状とは何かを持っていますが、私は私が修正できる方法を見つけ出すことはできません勘を持っていますそれ（また、私はimage_dirs_to_samplesがtflearnに意味をなさない何かを返すことを期待する）。
