python - Trying to show graph and other details in TensorBoard on google-colab by ngrok but failed

Question

I trained a model, got a log file and show graph and other details in TensorBoard on my computer. It was successful and nothing wrong.

Then I tried to do it again on colab. I install ngrok and tensorboard on colab, upload the log file and call tensorboard to show information.

# Install tensorboardcolab,download and unzeip ngrok
!pip install tensorboardcolab
!wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip
!unzip ngrok-stable-linux-amd64.zip
print()

# Delete unuse file and folder
!rm ngrok-stable-linux-amd64.zip
!rm -f -r sample_data
!pwd
!ls
print()
# upload a log file from local
from google.colab import files
uploaded = files.upload()
!ls
print()

# start tensorboard on ngrok
get_ipython().system_raw('tensorboard --logdir /content --host 0.0.0.0 --port 6006 &')
get_ipython().system_raw('./ngrok http 6006 &')
!curl -s http://localhost:4040/api/tunnels | python3 -c \
    "import sys, json; print(json.load(sys.stdin)['tunnels'][0]['public_url'])"

Below is the output after I ran the above.

I got this in the link. It said "No dashboards are active for the current data set".

Here is the notebook on colab.

I have no idea why this happened. There is a valid tensorboard link so I guess ngrok worked fine. Checked TensorBoard tutorial but it focus on how to use in a local environment.

Can anyone help me with this? Any reply would be greatly appreciated.
