GLIBC_2.27 not found on Xenial GPU Docker image

[d00astro]

Describe the bug
"ERR could not load backend" when using the Docker image redislabs/redisai:latest-gpu-x64-xenial, and trying to load a TF model.
The image redislabs/redisai:1.0.3-gpu-x64-xenial has this issue too.

It seems to be specific to these images, as neither redislabs/redisai:latest-cpu-x64-xenial (Xenial CPU) nor redislabs/redisai:latest-gpu-x64-bionic (Bionic GPU) have this issue.

To Reproduce
Steps to reproduce the behavior:

1. Download minimal RedisAI multiplication example TF model : graph.pb
2. docker run -d --rm --gpus all --name redisai -p 6379:6379 redislabs/redisai:latest-gpu-x64-xenial
3. cat graph.pb | redis-cli -x AI.MODELSET mymodel TF CPU INPUTS a b OUTPUTS c BLOB
(error) ERR Could not load backend
4. docker logs redisai

Environment (please complete the following information):

• OS: Host: Ubuntu 20.04 + Docker image: 16.04
• Version: 1.0.3 (?)
• Platfrom: x86
• Runtime: GPU (CC 6.1) / Cuda 10.1 / NCCL 2.8.3 / CuDNN 7.6.5

Additional context
Not critical for me as I can use Bionic just as well

@d00astro thanks for reporting!
we will check it out

@d00astro Thanks for reporting this. At first glance it looks like it could be the result of a dependency. Running strings against the shared object, I get the list below (note the lack of 2.2.27). I checked our shared objects, and we're similarly missing this version of glibc.

GLIBC_2.6
GLIBC_2.15
GLIBC_2.11
GLIBCXX_3.4.19

I'll check upstream in the future. For now, please keep using the docker you're currently content with.
