修改C:/user//.wslconfig

# Settings apply across all Linux distros running on WSL 2
[wsl2]

# Limits VM memory to use no more than 4 GB, this can be set as whole numbers using GB or MB
memory=4GB 

# Sets the VM to use two virtual processors
processors=2

# Specify a custom Linux kernel to use with your installed distros. The default kernel used can be found at https://github.com/microsoft/WSL2-Linux-Kernel
kernel=C:\\temp\\myCustomKernel

# Sets additional kernel parameters, in this case enabling older Linux base images such as Centos 6
kernelCommandLine = vsyscall=emulate

# Sets amount of swap storage space to 8GB, default is 25% of available RAM
swap=8GB

# Sets swapfile path location, default is %USERPROFILE%\AppData\Local\Temp\swap.vhdx
swapfile=C:\\temp\\wsl-swap.vhdx

# Disable page reporting so WSL retains all allocated memory claimed from Windows and releases none back when free
pageReporting=false

# Turn off default connection to bind WSL 2 localhost to Windows localhost
localhostforwarding=true

# Disables nested virtualization
nestedVirtualization=false

# Turns on output console showing contents of dmesg when opening a WSL 2 distro for debugging
debugConsole=true

可以适当增加内存，保证深度学习内存的分配。
然后在cmd中
wsl --shutdown
重启即可达到效果。

可以解决一部分的 Kernel Restart的问题
