Exception: argument --input: conflicting option string: --input

[BermineCN]

When I try to run the rl_nstep.py with the given data irregular100.mat, I met the following error. It seems that the 'input' argument has been defined somewhere besides the tf.flags. On the other hand, if I run this python file with the given data irregular10.mat, it is OK. I'm feeling doubtable. Could somebody tell me why? Thanks in advance.

We haven't tried on Windows machine yet, the error message indicates some problems with input arguments, Can you check the directory path and if file correctly located?

I have one problem when I use the trained model to make predictions according to new data. Firstly, I trained the model in the file irregular/RL with the given data, and used the tf.train.Saver to save the structure. The code to save the model is added to the rl_nstep.py as follows. I got the following 4 documents.
saver.save(sess, './gvin')

In another python script, I use the following code to restore the trained model.

with tf.Session() as sess:
  new_saver = tf.train.import_meta_graph('./gvin.meta')
  new_saver.restore(sess, tf.train.latest_checkpoint('./')
  #sess.run(tf.local_variables_initializer())

I got the following error message.
FailedPreconditionError (see above for traceback): Attempting to use uninitialized value q/p_0/fc_1/weights
If I uncomment the following code
sess.run(tf.local_variables_initializer())
The error message becomes to the following:
FailedPreconditionError (see above for traceback): Attempting to use uninitialized value q/p_8/fc_2/weights
I'm really curious about this since the saver should have saved the values of all the weights. Could you tell me why? The following is the whole error message information.
