google-colaboratory

问题 I have a code which works in python3.5 but will throw errors in python>3.5 but with !python --version in google colab return python 3.6.9, is there any way I can force google colab to use 3.5. I found some solutions in Stackoverflow which asked me to use local run time which won't be useful for me because I don't have enough computational resources in my local machine. 来源： https://stackoverflow.com/questions/59788607/how-to-force-google-colab-to-run-in-particular-python-version
