GAN model issue

[ShailendraLowanshi24]

I saw your comment on saving and load GAN model , I'm working on Generating Own dataset using GAN from these link https://www.analyticsvidhya.com/blog/2021/04/generate-your-own-dataset-using-gan/
And I want to train it for 20K epochs for good images, but colab is crashing.
I want your help in saving the model after every 1000 epochs and then used the saved model to start training for another 1000 epochs till i reach 20K.

Please help me. Thank you in advance
