           reference:

          solution 1 : increase shm-size

          2. Command : GPU=nvidia0 gpu-docker run --name=Fastai --shm-size=16G -d -p 8888:8888 paperspace/fastai:1.0-release
            (shm-size depends on the real memory size, suggest only using half memory for shm)
          3. Open Container Station, and get into Fastai Container

          issue2 : CUDA Out of Memory Error

          reference :

          solution: modify batch size

          1. modify Python code ，add "bs=16" into DataLoader


          issue3: ModuleNotFound

          solution: add module

          1. get into Jupyter notebook
          2. open Terminal

          3. pip install
            ex. : pip install dataclasses
          4. if package dependency issue, install accordingly
