Hi there, a problem occured when running the bam/run_classifier.py.

Tensorflow seems to lock the events.out.tfevents file until the whole program end, when execute the command utils.rmkdir(config.checkpoints_dir) at run_classfier.py line 271, tf.gfile.DeleteRecursively appears to can't be done and raise the error given below

Traceback (most recent call last):
  File "D:/bam/run_classifier.py", line 281, in <module>
    tf.app.run()
  File "C:\Python36\lib\site-packages\tensorflow\python\platform\app.py", line 125, in run

The enviroment currently use : tensorflow-gpu 1.13.1 windows10.
However, when run this code on centos, the problem doesn't exist.
Really hope to give me some advice

Following the steps in the repo, I am trying to run command python -m bam.run_classifier debug-model $BAM_DIR '{"debug": true}' as a minimal test. However, below line of code, raise Extra data: line 1 column 5 (char 4) error. Do you have any idea what should be the root cause? I tried to run other commands, still, this line raises an issue with the JSON.

Line raining the error:
\bam\run_classifier.py", line 258, in main config = configure.Config(topdir, model_name, **json.loads(hparams))

Error:
raise JSONDecodeError("Extra data", s, end) json.decoder.JSONDecodeError: Extra data: line 1 column 5 (char 4)
