# LeWM TTS Project

## Overview
Adapting LeWM (LeWorldModel) JEPA architecture for Text-to-Speech synthesis.
- Paper: https://le-wm.github.io/
- Project folder: `/home/ubuntu/lewm-tts`
- Goal: 10-20 speaker multi-speaker TTS on this 14M→24M model

## Architecture (v3c — Current)
- **TextEncoder**: Byte-level char transformer (4 layers, 256d, 4 heads)
- **AudioEncoder**: 1D CNN + Transformer (4 layers) → mu/logvar → reparameterization
  - **downsample_factor**: configurable (2 or 4), stored in config dict
- **JEPAPredictor**: Transformer decoder (6 layers) with causal self-attn + cross-attn to text + **KV-cache**
- **MelDecoder**: Linear→512 + ConvTranspose1d + ResConvBlock residual blocks + refinement conv
  - **upsample_factor**: matches downsample_factor
- **Vocoder**: Direct Vocos decode (model outputs 100 mels matching `charactr/vocos-mel-24khz`)
- **4 losses**: prediction (MSE), KL (Gaussian reg), reconstruction (L1 mel), multi-resolution spectral loss
- **Speaker embedding**: support for n_speakers > 1 (not yet trained)
- **KL annealing**: ramps up over first 20% of training
- Mel preprocessing matches Vocos exactly (verified: mel diff = 0.0000)

## Training Runs
- **v3** (4x downsample, kl=0.1, recon=1.0, spec=0.5): 24M params. Robotic + noise.
- **v3b** (4x downsample, kl=0.01, recon=2.0, spec=1.5): 24M params. Voice audible but noisy at ep90 (recon=0.56). Killed at ep96.
- **v3c** (2x downsample, kl=0.01, recon=2.0, spec=1.5): 21.1M params. **Currently training** at output_v3c/. ~41s/epoch. At ep110 recon≈0.54, voice coming through with noise.

## Key Findings (This Session)
- **KL weight 0.1 too aggressive** — crushes latent space, mel decoder can't reconstruct sharp formants
- **4x downsample bottleneck** — decoder must hallucinate fine detail for 4 frames per latent. 2x is better.
- **Model error is structured** (blurred formants), not random — L1=0.51 model recon sounds worse than L1=0.84 random noise on GT mel

- Mel config: n_fft=1024, hop=256, n_mels=100, sr=24000, f_max=None, power=1.0, clip_val=1e-7

## Next Steps

## LeWM TTS — v5 Training Status

**v5_pred_mask run just completed** — 200/200 epochs, 10,600 steps.

| Metric | Final Value |
|--------|------------|
| **pred_loss** | ~0.636 (best: 0.6354) |
| **dur_loss** | ~0.025 |
| **grad_norm** | 0.27–0.70 |
| **epoch time** | ~36s |

**Observations:**
- pred_loss plateaued around 0.636 for the last ~20 epochs — not improving
- No checkpoints directory exists (only logs + config) — checkpoints may have been cleaned or saved elsewhere. The log says `Saved: output_v5_pred_mask/checkpoints/epoch_0200.pt` but the directory is missing.
- This is a new "v5_pred_mask" variant vs the v3c run in memory — uses `codec_dim=128`, `ema_decay=0.998`, and a `roundtrip_weight`

**Compared to earlier runs:**
- v3b had recon_loss ~0.54–0.56 (different loss formulation)
- v5 uses pred+dur+roundtrip losses instead of pred+KL+recon+spectral

The checkpoints directory is missing — want me to investigate where they went, or are you ready to evaluate/move to the next step?

No `.pt` files anywhere in the repo, and no `checkpoints` directory exists. The log says it saved 20 checkpoints (every 10 epochs), but they're all gone.

The training finished at ~21:42 on Mar 24. Either:
1. The save code had a bug (wrote relative paths from wrong CWD)
2. Something cleaned them up after training

Let me check the train script to see how saves work.

The code does `ckpt_dir.mkdir(parents=True, exist_ok=True)` and uses `Path(args.output_dir) / "checkpoints"` — that's a relative path. Let me check where the training was launched from.


find /home/ubuntu -path "*/output_v5_pred_mask/checkpoints" -type d 2>/dev/null; find /home/ubuntu -name "epoch_0200.pt" 2>/dev/null

Search for checkpoints anywhere on disk


find /home/ubuntu -name "*.pt" -type f 2>/dev/null | head -20

Find any .pt files on disk


**All checkpoints are gone.** No LeWM `.pt` files exist anywhere on the machine. The log printed "Saved" 20 times, but the `checkpoints/` directory was never created (or was deleted).

Most likely cause: the training script was run from a directory where the relative path `output_v5_pred_mask/checkpoints/` resolved to a different location (e.g., inside a container or temp filesystem), or the save silently failed without raising an error. The log says `Saved:` but the train script just prints that string — let me check if it catches errors.

Wait — the log says `Saved: output_v5_pred_mask/checkpoints/epoch_0190.pt` (relative path), but `train.py` line 194 prints `Saved checkpoint:` while `train_v5_pred.py` line 263 prints `Saved:`. Let me check which one actually ran.


Check log header for launch command

This ran `train_v5_pred.py` loading from `output_v5/checkpoints/epoch_0120.pt`. That pretrained checkpoint is also gone now. The `torch.save` calls used relative paths and didn't error — meaning the directory *was* created and files *were* saved during training, but something deleted them after.


Check disk space


/dev/sda2       984G  302G  642G  32% /


**Summary: All checkpoints from v5_pred_mask (and the earlier v5 run) have been deleted.** The training did save them successfully (the directory was created, `torch.save` would have thrown an error otherwise), but they no longer exist on disk. Disk space is fine (642G free), so it wasn't an auto-cleanup due to space pressure.

Possible causes:
1. Manual `rm` or cleanup script ran after training
2. Another process or cron job cleaned up `.pt` files

Unfortunately, **the v5_pred_mask run will need to be retrained**. The config and logs are intact, so it's reproducible. Want me to kick off a new training run?


can u check how many pods running and what is cost that we for running pipecat in gke


kubectl get pods --all-namespaces 2>&1 | head -50

List all pods in GKE

Calculate total resource requests


Total pod resource requests: 240.0 vCPU, 360.0 GB RAM
Per pod: 2.00 vCPU, 3.00 GB RAM


Here's the breakdown:

## GKE Pipecat Cluster Status

| | Count/Spec |
|---|---|
| **Pipecat pods** | **120** running (all healthy) |
| **Datadog agents** | 7 (DaemonSet, 1 per node) |
| **Nodes** | 7x `n1-standard-64` (64 vCPU, 236 GB each) |
| **Per pod** | 2 vCPU, 3 GB RAM requested |
| **Total pod usage** | 240 vCPU, 360 GB RAM |

## Estimated Cost

| Resource | Cost |
|---|---|
| **7x n1-standard-64** | ~$2.12/hr each = **~$14.84/hr** |
| **Monthly (24/7)** | **~$10,685/mo** |
| **GKE management fee** | ~$73/mo (standard tier) |
| **Networking/LB** | varies |
| **Total estimate** | **~$10,800–$11,000/mo** |

That's 7 beefy nodes running 24/7 for 120 pipecat pods. The nodes are at ~53% CPU utilization (240/448 total vCPU) and ~22% memory (360/1651 GB). You might be able to consolidate to fewer/smaller nodes if the pods don't burst much above their requests.

Now let me check which region your GKE cluster is in to see actual usage there.

Interesting — your GKE cluster is actually in **asia-south1** (Mumbai), not in a US region. That's why all US regions show **0 used**.

Here's the vCPU quota summary across US regions:

| Region | CPUS (N1) | N2 | E2 | C2 | C2D | Other |
|--------|-----------|-----|-----|-----|------|-------|
| **us-central1** | 0/200 | 0/200 | 0/72 | 0/100 | 0/100 | T2A: 0/96 |

| **us-east4** | 0/200 | 0/200 | 0/72 | 0/100 | 0/100 | T2A: 0/96 |
| **us-east5** | 0/100 | 0/200 | 0/72 | 0/100 | 0/100 | — |
| **us-south1** | 0/100 | 0/200 | 0/72 | 0/100 | 0/100 | — |
| **us-west1** | 0/100 | 0/100 | 0/72 | 0/24 | 0/100 | T2D: 0/100 |
| **us-west2** | 0/200 | 0/100 | 0/72 | 0/100 | 0/100 | — |
| **us-west3** | 0/200 | 0/100 | 0/72 | 0/100 | 0/100 | — |
| **us-west4** | 0/200 | 0/200 | 0/72 | 0/100 | 0/100 | — |

**All US regions have 0 vCPUs in use.** Your pipecat cluster (448 vCPUs across 7x n1-standard-64) is running in **asia-south1-a** (Mumbai). Want me to check the asia-south1 quota too?

Here's what you have available:

## US Region vCPU Quotas (all unused)

| Region | N1 | N2 | E2 | C2D | **Total** |
|--------|-----|-----|-----|------|-----------|
| **us-central1** | 200 | 200 | 72 | 100 | **572** |
| **us-east1** | 200 | 200 | 72 | 100 | **572** |
| **us-east4** | 200 | 200 | 72 | 100 | **572** |
| us-west1 | 100 | 100 | 72 | 100 | **372** |

## What you need

Your current asia-south1 pipecat setup uses **448 vCPUs** (7x n1-standard-64). To replicate the same setup in the US:

- **N1 quota of 200 isn't enough** — you need 448 N1 vCPUs
- You'd need to either:
  1. **Request a quota increase** to ~500 N1 vCPUs in your target US region (us-central1 or us-east1 are best for latency)
  2. **Use N2 machines instead** — split across N1 (200) + N2 (200) = 400, still short
  3. **Run fewer/smaller nodes** in the US if this is a lighter deployment

For reference, asia-south1 has a 500 N1 quota which is why it works there.

Want me to submit a quota increase request for a specific US region?

**Redis is up and running.** Here's the summary:

| | Details |
|---|---|
| **Status** | Healthy (PONG) |
| **URL** | `redis://10.222.58.99:6379/0` |
| **Type** | Internal IP (likely a GCE VM or StatefulSet, not Memorystore) |
| **REDIS_ENABLED** | `true` in pipecat deployment |
| **Secret** | `maya-redis-secret` |

It's accessible from within the cluster. Not running as a GKE pod or Memorystore — probably a standalone Redis on a GCE instance at `10.222.58.99`.
