RuntimeError: [/build/VisualDL/visualdl/storage/storage.cc:43]

I am using VisualDL and I get the following error. How should I troubleshoot

File "/usr/local/lib/python2.7/dist-packages/visualdl/python/storage.py", line 141, in scalar
return type2scalartype
RuntimeError: [/build/VisualDL/visualdl/storage/storage.cc:43]

@zhangguangzhi Looking at the code history. I think storage.cc:43 is as following

Tablet Storage::AddTablet(const std::string& x) {
  CHECK(tablets_->count(x) == 0) << "tablet [" << x << "] has existed";

Maybe you were trying to create a new Scalar Writer with the same tag name within the same mode
Try change the mode name like this

logw = LogWriter(logdir, 200000)

# create scalars in mode train and test.
with logw.mode('train') as logger:
    scalar0 = logger.scalar("scratch/scalar")

with logw.mode('test') as logger:
    scalar1 = logger.scalar("scratch/scalar")

Hope this helps

@jetfuel Thank you, this is the reason.
