Question

用于初始化MonitoredTrainingSession的代码会导致InvalidArgumentError：

with tf.train.MonitoredTrainingSession(
    server.target,
    is_chief=is_learner,
    checkpoint_dir=FLAGS.logdir,
    save_checkpoint_secs=600,
    save_summaries_secs=30,
    log_step_count_steps=50000,
    hooks=[py_process.PyProcessHook()],
    config=config) as session:

这是回溯：

Traceback (most recent call last):
  File "/Users/hughalessi/miniconda3/envs/rl/lib/python3.5/site-packages/tensorflow/python/client/session.py", line 1334, in _do_call
    return fn(*args)

tensorflow.python.framework.errors_impl.InvalidArgumentError: Input 1 of node scan/while/Merge_5 was passed double from scan/while/NextIteration_5:0 incompatible with expected float.

这是一个使用自定义环境的环境，该环境是为Google的IMPALA架构实现可伸缩代理构建的。这是存储库的链接： https://github.com/deepmind/scalable_agent

创建MonitoredTrainingSession会在张量流中导致InvalidArgumentError
