Description
Previous container only supports up to py3.6 which TF2.7 is not built for. TF team has stopped publishing these custom-op images since TF2.5.
Using the CUDA image makes the container larger, but it still uses the cpu only version of TF so it's accurate to call it dev_cpu. Building the gpu image would be pretty trivial now, but also this limits the maintenance burden on our team.
There is no multipython container without GPU installs:
