edgetpu: Internal compiler error. Aborting!

I am facing an unusual problem. When I try to compile my model it throws me Internal compiler error. Aborting! error.

But I noticed sometimes I try running the same command again and again, it compiles after a few attempts.

Output model: ModelDIR/model-quant_edgetpu.tflite
Output size: 3.33MiB

Number of Edge TPU subgraphs: 1
Total number of operations: 34
Operation log: ModelDIR/model-quant_edgetpu.log

Model successfully compiled but not all operations are supported by the Edge TPU. A percentage of the model will instead run on the CPU, which is slower. If possible, consider updating your model to use only operations supported by the Edge TPU. For details, visit g.co/coral/model-reqs.
Number of operations that will run on Edge TPU: 5
Number of operations that will run on CPU: 29
See the operation log file for individual operation details.

Can someone explain this behavior ?
