Trying to use Tensorboard on Google Colab
The page below gives informations about Tensorboard:
https://pytorch.org/docs/stable/tensorboard.html
I am using Google Colab and when i write the following
instructions(which are in the link above):
!pip install tensorboard
tensorboard --logdir=runs

it sends me the following error message:
 File &quot;&lt;ipython-input-111-949c7e8e565e&gt;&quot;, line 2
tensorboard --logdir=runs
                         ^
SyntaxError: can't assign to operator

so when i copy paste their
own example:
from torch.utils.tensorboard import SummaryWriter
writer = SummaryWriter()
x = range(100)
for i in x:
    writer.add_scalar('y=2x', i * 2, i)
writer.close()

it does not return the expected graph.
Could someone help me fix this problem?Thank you in advance!

As explained in How to use Tensorboard with PyTorch in Google Colab.
In Google Colab you should start Tensorboard magic at the start of your code with:
%load_ext tensorboard

and after you define a summary file you need to insatiate Tensorboard with
%tensorboard --logdir $tensorboard_dir

where Tensorboard dir is a script variable of type str indicating where the summary file is.
