make error in Tensorflow Lite Micro 
Hi @abcd123abcd ,

I tried replicating your error but i kept running into library issues. Can you please update your python version and then try installing tflite micro and let me know if the issue still persists for you . This issue is stale because it has been open for 7 days with no activity. It will be closed if no further activity occurs. Thank you. This issue was closed because it has been inactive for 7 days since being marked as stale. Please reopen if you'd like to work on this further. Are you satisfied with the resolution of your issue?
