@sazzad16if you can fix the error

we can approve.

@filipecosta90 We should do it outside this PR. I can see that @DvirDukhan is trying in #29. But it is generating

com.redislabs.redisai.RedisAIException: redis.clients.jedis.exceptions.JedisDataException: ERR Could not load backend
	at com.redislabs.redisai.RedisAITest.testSetModelFromModelTFLite(RedisAITest.java:202)
Caused by: redis.clients.jedis.exceptions.JedisDataException: ERR Could not load backend
	at com.redislabs.redisai.RedisAITest.testSetModelFromModelTFLite(RedisAITest.java:202)

Is there any change in TFLITE?

1. This PR is Irrelevant as script execute command redis-inference-optimization#682 will be merge soon
2. We have a docker issue with TFLite - fixed at docker build - change buster to bionic redis-inference-optimization#707

@filipecosta90 The issue is in RedisAI docker TFLITE. That's out of my hand.
