[CI] Jenkins workers has old tflite package

[apivovarov]

1 day ago I updated ubuntu_install_tflite.sh to use tflite schema version 1.13
https://github.com/dmlc/tvm/blob/master/docker/install/ubuntu_install_tflite.sh#L38
PR was merged 1 day ago
#3356

After that I started two build which uses new tflite classes from v1.13
Both builds failed because they can not find new tflite classes which means that Jenkins workers still use old tflite v1.12

@tqchen Can you help me to solve the issue with old tflite package on Jenkins workers?

[tqchen]

The CI image uses a cached image, and need to be staged manually. This is to ensure we have a stable build env. See note here: https://docs.tvm.ai/contribute/pull_request.html#ci-environment

However, do expect a bit delays as we want to update the images infrequently, and there might be consistency issues when updating the docker image

A quick way to get around would make sure that the solution can be compatible with both versions (also helpful for users as well). This will also be helpful as the change of the state might be compatible: we need to change the image and the test at the same time and sometimes it breaks things

I will send an update note when the docker image gets updated.

ok, I fixed my PR to support both tflite versions 1.12 and 1.13

Now that #3374 has been merged, the CI should have been updated to the latest state including the tflite change
