Can't create docker

[bj32161]

Hi,
I did install Docker version 18.09.7 on my Ubuntu 18.04. I did follow your instruction to install docker image as this command
$docker build -t colemurray/age-gender-estimation-tutorial
I got this error
"docker build" requires exactly 1 argument.
See 'docker build --help'.
Any advice?
Thank you.

Hello @bj32161,

I believe you are missing the directory as part of dockers build command

# CPU:
docker build -t colemurray/age-gender-estimation-tutorial .

# GPU
docker build -t colemurray/age-gender-estimation-tutorial -f Dockerfile.gpu .

Note the '.' refers to the current directory
