如何找出你是否有colab在colab里面？

Question

这是一个更复杂的问题，但是否有这样做的功能？我只是找不到关于这个主题的任何文档。例如，我的用法如下：

from google.colab import utils # I made this up
colab_pro = utils.colab_is_pro()
if colab_pro:
  # train model with higher settings
else:
  # train model with lower settings

目前，我确实有办法做到这一点，但这是相当麻烦的：

gpu_name = !nvidia-smi --query-gpu=gpu_name --format=csv
# You get Tesla T4 with free colab and faster GPUs with colab pro
colab_pro = False if 'T4' in gpu_name else True

FYI，这是我正在做的实验室：https://colab.research.google.com/github/Namburger/edgetpu-ssdlite-mobiledet-retrain/blob/master/ssdlite_mobiledet_transfer_learning_cat_vs_dog.ipynb#scrollTo=Mg1C8UwStK7i

Answer 1

#A Colab pro environment should have >20Gb of total memory.
from psutil import virtual_memory
colab_pro = virtual_memory().total / 1e9
print('Your runtime has {:.1f} gigabytes of available RAM\n'.format(colab_pro))

if colab_pro < 20:
  print('Not using a high-RAM runtime')
  # train model with lower settings
else:
  print('You are using a high-RAM runtime!')
  # train model with higher settings

此外，您可以检查colab中的可用内存，如下所示：

!cat /proc/meminfo

一个Colab环境应该有>20 of的总内存。
