 ## Troubleshoot
-Those who are suffer from out of bound index issue, please refer this [issue](https://github.com/mks0601/PoseFix_RELEASE/issues/8). According to [TF docs](https://www.tensorflow.org/api_docs/python/tf/scatter_nd), `tf.scatter_nd` will ignore out of bound indices in GPU mode. However, `BruceLeeeee` had a issue with that and fixed by clipping coordinates.

+2. For those who suffer from `FileNotFoundError: [Errno 2] No such file or directory: 'tmp_result_0.pkl'` in testing stage, **please prepare human detection result and input pose properly**. The pkl files are generated and deleted automatically in testing stage, so you don't have to prepare them. Most of this error comes from inproper human detection file.
