title: saving plt subplot in google drive
body: <p>I am running my code on Google Colab which I have uploaded my files on my google drive. For more information, I connect to my google drive by:</p>
  <pre><code>from google.colab import drive
  drive.mount('/content/gdrive')
  </code></pre>
  <p>I have a piece of code for showing some figs for any epochs. It shows figs well. I have write it as:</p>
  <pre><code>img_plt=imgs.cpu().numpy()
  true_masks_plt=true_masks.detach().cpu().numpy()  
  masks_pred_plt=masks_pred.detach().cpu().numpy()  
  input=np.squeeze(np.moveaxis(img_plt,1,-1))
  gt=np.squeeze(np.moveaxis(true_masks_plt,1,-1))
  pd=np.squeeze(np.moveaxis(masks_pred_plt,1,-1))
  _,figs=plt.subplots(1,3,figsize=[15,5])
  figs[0].imshow(input[0])
  figs[1].imshow(pd[0])
  figs[2].imshow(gt[0])
  
  figs[0].set_title(f'input image ')
  figs[1].set_title(f'mask prediction')
  figs[2].set_title(f'true mask')
  plt.show()
  </code></pre>
  <p>Now, I would like to save these three images on my google drive. How should I do that?</p>
