Problems when I load the pretrained model

[douyh]

I know very little about tensorflow.

I use this code...from the Internet... and try to load the pretrained model W30.

  import tensorflow as tf
  from net.model import HRNet
  import horovod.tensorflow as hvd
  
  
  def load_model(meta, checkpoint_dir):

       with tf.Session() as sess:
          saver = tf.train.import_meta_graph(meta)
          saver.restore(sess, tf.train.latest_checkpoint(checkpoint_dir))
          # graph = tf.get_default_graph()
          # fc = graph.get_tensor_by_name('final_dense')
          # print(fc.shape)
 
 
 
  if __name__ == "__main__":
      load_model('model/model.ckpt-1000000.meta', 'model')

I got an error

I add import horovod.tensorflow as hvd because I met a KeyError 'HorovodAllreduce'

What should I do? Thanks for your reply.
