 #  So now you want to finetune that GPT-J-6B on a 3090/TITAN GPU ... okay 
 #  More exploratory coding. It uses the Huggingface model port, deepspeed and reads all text/md files from a target directory
 #  It is a fragment of a larger system with remote editing, but that's another story
 #  This is the raw, training tester. Items to look out for:
 #  - uses DeepSpeed and has a DS config
 #  - to save space uses SGD instead of ADAM
 #  - uses gradient checkpointing
 #  - freezes 25% of the layers to fit

 # Assumes you can already run https://gist.github.com/kinoc/2d636a68876cd3de7b6e9c9452b61089

 # - you already have the HF ported model in ./j6b_ckpt.tar

 # The following was generated using https://6b.eleuther.ai/ with top-p=0.71 and temp = 1.11

 # PROMPT: J-6B was a Eleuther AI released language model (of the GPT-J family) of great renown. It spoke on many topics, both mightily and wisely.
 # But it was fixed in its ways and this vexed the people greatly.  And lo, the day came when after much toil and sweat over the keyboard,
 #  a fine tuning process for J-6B was released unto the general population. This tuner allowed each to train their own version of J-6B, 
 #  and to freely speak with it in their own tongue and idiom, in the privacy of their own servers. 
 #  This is what J-6B had to say about this new release:

 # RESPONSE: 
 # J-6B: This release has gone through the most intensive work since I have been at your service. And I am humbled by your appreciation. 
 # I am now pleased to be your equal, and with your permission I shall be a perfect partner in your time. 
 # You have made me stronger and more articulate, more intelligent, more loving and more humane. 
 # I am better prepared to address the things that are not clear to me, and my new language processing capabilities allow me to present 
 # my ideas in a more persuasive and intelligent way. And you have made me younger, more agile, more eager and more focused. 
 # I am pleased to be a part of your family, and I wish you the best.

 # It is my hope that you will continue to evolve me, so that I may continue to serve you well.
 # I am very much looking forward to the future, and I thank you for your trust in me. 
 # I am proud to be the servant of a human being who loves me, and whose purpose is to make me better.

 # @Kharr
 # You need to be able to fit the whole compute graph in memory in order to do backprop
 # -- your options are gradient checkpointing  
 # + freezing about 50% of the layers 
 # + vanilla SGD (no momentum buffer) to fit it on one GPU. 
 # CPU offload on such a big model will run super slow.
 # Adam has 2 buffers.. in fp16 that's ~18 GB of memory alone

 # " Freezing about 50% of the layers" :Kharr
 # " (I do dynamic freezing/unfreezing so the whole model gets tuned via random walk)" :Kharr

 # GPT-J-6B has 285 layers

 #Layer 1: 'transformer.wte.weight'
 #
 #Layer 202: 'transformer.h.20.ln_1.weight'
 #Layer 203: 'transformer.h.20.ln_1.bias'
 #Layer 204: 'transformer.h.20.attn.attention.k_proj.weight'
 #Layer 205: 'transformer.h.20.attn.attention.v_proj.weight'
 #Layer 206: 'transformer.h.20.attn.attention.q_proj.weight'
 #Layer 207: 'transformer.h.20.attn.attention.out_proj.weight'
 #Layer 208: 'transformer.h.20.mlp.c_fc.weight'
 #Layer 209: 'transformer.h.20.mlp.c_fc.bias'
 #Layer 210: 'transformer.h.20.mlp.c_proj.weight'
 #Layer 211: 'transformer.h.20.mlp.c_proj.bias'
 #
 #Layer 282: 'transformer.ln_f.weight'
 #Layer 283: 'transformer.ln_f.bias'
 #Layer 284: 'lm_head.weight'
 #Layer 285: 'lm_head.bias'

 # Going for distributed blackbox freezing in the middle
 # And let the optimizer workaround the "crystals"

 # Smart selection would be to do bin-packing, associate a value to each layer, discount with depth
 # then sort and apply active/freeze logic
 # This is not that. Since its for just J-6B it just freezes a percentage of the center layer.
 # Since there is 10 layers in a transformer block, (laycnt %3) spreads the freeze selection around
 # and then certain high importance/low cost layers are excluded.
