RuntimeError: CUDA error: out of memory
CUDA kernel errors might be asynchronously reported at some other API call,so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
```

**Steps/Code to reproduce bug**
1. Copy the ipynb to a server with a GPU and install CUDA 11.6, CuDNN 8.4.1 , PyTorch 1.12.1
2. Install Nvidia Apex and run all the command listed in the first block
3. Run every block till `%%time
trainer.fit(char_model)`


**Expected behavior**

Start training as what I've seen when running in colab.
