Can't update loss with MeterLogger.

[TuXiaokang]

this was caused by error indent in #85

[TuXiaokang]

same problem with updateMeter #78

[szagoruyko]

oops, sorry! will fix now

[kuixu]

@TuXiaokang What's the type of the loss you used in mlog.updateLoss() ? Variable or Tensor?
There is another example may contribute to you.

@szagoruyko #printMeter is still has not be fixed.

btw, there comes another problem when i run pytorch_online_ploter:

I have no idea how to address it.

@TuXiaokang Check your Visdom port. It seem that your port is the right one.
You could run by

python -m visdom.server # default port is 8097
CUDA_VISIBLE_DEVICES=1 python mnist.py --port 8097

Or

python -m visdom.server -port 9999
CUDA_VISIBLE_DEVICES=1 python mnist.py --port 9999

@barrykui it works, thank you!

i hope it can plot charts on different env not only main.

[kuixu]

Me too. haha.
MeterLogger only provide plot line and confusion matrix. If you have some idea about plotting charts, tell me or contribute to tnt.

For different env, you could set keywords in the title option in mlog = MeterLogger(server="Server's IP", nclass=10, title="keywords"), and then filter the keywords in visdom.
