I installed tensorboard_pro, but the page cannot be displayed normally in jupyter lab

[xudamao2015]

When I click [create TensorBoard] button in jupyter lab, the tensorboard page cannot be displayed normally.

I also tried other version such as tensorflow 2.12, jupyterlab 3.2.8. It also doesn't work.
Python version is 3.8.12

------ installed packages --------
jupyterlab-tensorboard-pro 0.7.0
tensorboard 2.13.0
tensorflow 2.13.0rc0
jupyterlab 3.6.1

I started jupyter lab using --debug option, there are no error in log.

When I started tensorboard using 'tensorboard --logdir . --bind_all', the page could be rendered normally.

jupyterlab-tensorboard-pro 0.7.0
tensorboard 2.10.0
tensorflow 2.10.0
jupyterlab 3.0.16
python3.8

收到你的问题，我今天晚些时候尝试复现一下

感谢

已定位问题原因。
是tornado版本问题，需要回退到6.2，我之前有问题的版本是6.3.2

tornado 6.3+ 是近期新发的版本，这里可能存在兼容问题，后续我进一步跟进下。

我安装了插件之后一直在initializing
我的环境是
python:3.7
TensorFlow-gpu=2.3.1
IPython : 8.13.2
ipykernel : 6.23.0
ipywidgets : 8.0.6
jupyter_client : 8.2.0
jupyter_core : 5.3.0
jupyter_server : 2.5.0
jupyterlab : 3.6.3
nbclient : 0.7.4
nbconvert : 7.4.0
nbformat : 5.8.0
notebook : 6.5.4
qtconsole : 5.4.3
traitlets : 5.9.0

tornado 6.3 之后的异步写法发生了变化，我在这个分支完成了适配：https://github.com/HFAiLab/jupyterlab_tensorboard_pro/tree/feat/tornado_6.3

后续还需要进行一点测试再发布正式版本，暂时先对当前版本的插件依赖的 tornado 加了 6.2 的约束。
