Second Edition Code

[Ascrypto]

Hello,

when running ./02_a3c_data.py --cuda -n final, I got errors related to tensorboard.
ImportError: TensorBoard logging requires TensorBoard with Python summary writer installed. This should be available in 1.14 or above. I do have the package installed.

I tried to import tensorboardx, but it did not work either.

Packages versions:
torch==1.7.0
tensorboard==2.7.0
ptan==0.7
tensorboardX==2.4.1

Note: tensorboard is functional when executing tensorboard --logdir=runs

For the cuda's arguments, is "final" a typo. If not, what does it do? (I could not find any information about it).

Another important note: my ec2 instance I am using has no GPU.
