If so, how?\r\nNo\r\n\r\n## Describe the issue\r\n\r\nThis is a sequel of the issues #723 that was closed 2 days back. I could have added this under same issue had it not been closed as both issues are related. #723 is about compiler errors occurred during running `pip install -r requirements.txt`.\r\n\r\nThis issue is about what we have observed when the requirements were installed in NAO Robot. We got into few issues as `emerge` package manager is not available in the NAO OS (supposed to be similar to opennao VM). \r\n\r\nThese are the steps followed in the installation.\r\n1. Check `pip `version =9.0.1 - OK\r\n2. Install `virtualenv `- OK\r\n3. Install `portaudio `using `emerge `– **Fail as emerge is not available in usr/bin**\r\n4. Install `pyaudio `using `emerge `– Not Started yet\r\n5. Install package as per requirements.txt\r\n        `grpcio==1.0.4` – Not Started yet\r\n        `PyAudio==0.2.9` – Not Started yet\r\n        `grpc-google-cloud-speech-v1beta1==0.14.0` – Not Started yet\r\n        `six==1.10.0` – Not Started yet\r\n        `requests==2.12.4` – Not Started yet\r\n        `google-auth==0.5.0` – Not Started yet\r\n6. `python transcribe_streaming.py` – Not Started yet.\r\n\r\nThen we copied the `portaudio `library (portaudio-19_pre20071207.tbz2) from opennao vm to Robot and ran `pip install`.\r\n\r\n```\r\n(env) nao [0] ~/googlespeech $ pip install -r requirements.txt\r\nCollecting PyAudio==0.2.9 (from -r requirements.txt (line 2))\r\n/var/persistent/home/nao/googlespeech/env/lib/python2.7/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:318: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform.
