The issue of enjoy_husky_navigate after it is trained

[Berk035]

Hello everyone,

I study on navigate examples of Gibson. I am trying to reach target position and something is missing. There is a wrong with enjoy_husky_navigate_ppo1.py while I am trying to apply my trained model. The error is shown below:

Error in atexit._run_exitfuncs: Traceback (most recent call last): File "/home/deepsrv/anaconda3/envs/py35/lib/python3.5/site-packages/gym/utils/closer.py", line 67, in close closeable.close() File "/home/deepsrv/PycharmProjects/Gibson_Env/gibson/envs/env_modalities.py", line 490, in _close self.r_camera_rgb._close() AttributeError: 'NoneType' object has no attribute '_close'

Also I met with this error at fuse_policy function. My model consists 3000 timesteps per actorbatch. How can handle with this error?

Thanks in advance.

I fixed the problem which is above. It is occurred due to 'out of memory' for CUDA. I closed some programs and it runs properly.

Unfortunately, I have a different problem with running model on enjoy_husky_navigate. I met with the error this time:

What is wrong this time?

I realized that training mode is different. So, it causes this error. But, I want to ask another thing.
How can I continue to training process with trained model file?
Is the code this one:
if reload name: saver = tf.train.Saver() saver.restore(tf.get_default_session(), reload name)

Thanks in advance.
