Tensorboard not having scalar tab

[timsu27]

hi,

I successfully installed & launched tensorboard but encountered a problem, shown as below.

this is the screen shot shown in jupyter notebook:

this is the screen shot using the native tensorboard:

As you can see there is missing a scalar tab, then I checked jupyter notebook server message:

I think its the tfevent not loading correctly for the filename having a .ipXXXX comes behind.

Hi @TimJLS , did you find a solution to this? Actually, you can open Scalar tab by pressing on "Inactive>Scalar", but I am curious why it happens.

[ptrnn]

Same here, the page doesn't show data but "No dashboards are active for the current data set" unless I manully switch to "Inactive -> Scalars"

The Scalar tab should work with TB >= 2.2 with #63 ; could you give that a try, please?
