Save, load and save again

Hi,

Thanks for this useful library!

I wonder how to do save - load - save - load multiple times? To achieve this, I use the code below:

if os.path.exists(log_path):
    load_logs(optimizer, logs=[log_path])
    print('Load {} records from disk.'.format(len(optimizer.space)))

logger = JSONLogger(path=log_path)
optimizer.subscribe(Events.OPTMIZATION_STEP, logger)

But it seems that this line

logger = JSONLogger(path=log_path)

will delete the orginal json file and previous records are lost.

Why do we need to do os.remove(self._path) in JSONLogger.__init__()?

Hi, While it’s not save you can just add the following lines in your code:

class newJSONLogger(JSONLogger) :

      def __init__(self, path):
            self._path=None
            super(JSONLogger, self).__init__()
            self._path = path if path[-5:] == ".json" else path + ".json"

For those who are wondering, the reset option from @AlbertAlonso isn’t available in v1.2.0 yet, so it doesn’t come with the installation from pip. In the meanwhile, thanks for this workaround!
