WikiText-103 100MB Attempt

Attempted to run training with 100MB of WikiText-103 data streamed via datasets and converted to bits. Converting the dataset (352k lines) took too long and the process was interrupted before the first training step could complete.

Offline Full Bits Training Attempt

• Installed requirements successfully.
• Built full_bits.pt (100MB WikiText-103 compressed to bits).
• Ran python full_bits_train.py but the training loop was extremely slow and was manually interrupted before completing a single pass.

BitSeq Dataset Training

• Built full_bits.pt from WikiText2 using build_full_bits.py.
• Ran python full_bits_train.py with BitSeq DataLoader (seq=2048, batch=8).
• The script loaded one batch and reported Batch loss: 2.4375.

Offline train_full_sequence Scale-Up (8 steps)

WikiText Training Attempt (2025-09-??)

Attempted minimal training on real WikiText-2 data using train_loop with dropout 0.1 and evaluation dropout 0.0. Training failed due to a telemetry shape mismatch:

RuntimeError: The size of tensor a (4) must match the size of tensor b (64) at non-singleton dimension 1

As a sanity check, ran hil_safe_inference on an untrained model in evaluation mode (dropout=0.0):

Inference output bits: [[0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]]
