installing anaconda and jupyter in digitalocean

I have been frustrated lately trying to learn data science in my office (in my spare time) because of the SSL certificate issue. Every time I execute a command the error just popping up and I get a less patient and I say "Arrrrrr" and suddenly just pop in my mind, what if I will run anaconda and jupyter in my external server which my personal from digital ocean. and then the quest begins....


1. install the anaconda

2. configure and run jupyter

ohhh, i'm invincible its only 2 steps.

speech recognition

its 11pm and I found something interesting, this time I tried to implement speech recognition.

actually, its very easy

1. pip install SpeechRecognition
2. conda install -c anaconda pyaudio
3. the code

import speech_recognition as sr

r = sr.Recognizer()

with sr.Microphone() as source:
print('Speak anything:')
audio = r.listen(source)

try:
text = r.recognize_google(audio)
print('you said: {}'.format(text))
except:
print('sorry could not recognize your voice...')


4. run it! so simple. Eureka!

solution:

conda config --set ssl_verify False
