Potential issues with MineCLIP weights

[nickioan]

I have loaded the weights on the MineCLIP model for both the attn and avg variants to observe how the generated reward varies when parsing a video from a user playing MineCraft following one of the provided tasks. It appears that the generated reward remains stagnant throughout the video regardless of the text prompt, in addition when using randomly generated frames or zeroed frames the output is still very similar.

I am fairly certain that my video loading and weight loading process is in accordance to the existing documentation, so I am wondering if the current uploaded weights for either variants is incorrect.

Hey there, thanks for your interest and raising the issue. Could you share more information such as the script you used so we can look into?

[nickioan]

Thank you so much for your timely response below I have included the main code to get the reward form our recorded video. Note we divide the reward by the logit_scale parameter to get the cosine similarity

Main code

import os
import torch
import torchvision
from torch.utils.data import DataLoader
import wandb
import yaml
from video_utils import (VideoDataset,
                         init_wandb,
                         load_mineclip,
                         example_read_video)

STREAM = 'video'

if __name__ == '__main__':
    import argparse
    # get the task name from the command line
    parser = argparse.ArgumentParser()
    parser.add_argument('--task', type=str, default='task1')
    args = parser.parse_args()
    TASK = args.task

    with open("tasks_conf.yaml", "r") as stream:
        try:
            conf = yaml.safe_load(stream)[TASK]
        except yaml.YAMLError as exc:
            print(exc)

    PATH = os.path.join(os.getcwd(), 'recordings', '{}.mp4'.format(conf['name']))
    prompts = conf['prompts']

    init_wandb(task_id=conf['name'])
    prompt_ids = ["Sub-Task {}".format(x+1) for x in range(len(prompts))]

    device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
    video = torchvision.io.VideoReader(PATH, STREAM)
    vf, info, meta = example_read_video(video)
    dataset = VideoDataset(vf)

    loader = DataLoader(
        dataset,
        batch_size=16,
        shuffle=False
    )
    model = load_mineclip(device)
    with torch.no_grad():
        prompt_feats = model.encode_text(prompts)
    for data in loader:
        data = torch.unsqueeze(data, dim=0).to(device)
        with torch.no_grad():
            reward, _ = model(data, text_tokens=prompt_feats, is_video_features=False)
            reward /= torch.exp(model.clip_model.logit_scale)
        log_data = dict(zip(prompt_ids, reward[0].cpu().numpy()))
        wandb.log(log_data)

In addition here are the main helper functions to load MineCLIP and the recorded video

Helper functions

import torch
import itertools
import torchvision
import torchvision.transforms as T
from torch.utils.data import Dataset
import hashlib
from omegaconf import OmegaConf
from mineclip import MineCLIP

def load_mineclip(device):
    # Initialize MineClip
    cfg = OmegaConf.load("clip_conf_simple.yaml")
    OmegaConf.set_struct(cfg, False)
    ckpt = cfg.pop("ckpt")
    OmegaConf.set_struct(cfg, True)
    assert (
        hashlib.md5(open(ckpt.path, "rb").read()).hexdigest() == ckpt.checksum
    ), "broken ckpt"
    
    model = MineCLIP(**cfg).to(device)
    model.load_ckpt(ckpt.path,strict=True)
    model.eval()
    return model

def example_read_video(video_object, start=0, end=None):
    transform = T.Resize((160,256))
    if end is None:
        end = float("inf")
    if end < start:
        raise ValueError(
            "end time should be larger than start time, got "
            f"start time={start} and end time={end}"
        )
        

    video_frames = torch.empty(0)
    video_pts = []
    video_object.set_current_stream("video")
    frames = []
    for frame in itertools.takewhile(lambda x: x['pts'] <= end, video_object.seek(start)):
        frames.append(transform(frame['data']))
        video_pts.append(frame['pts'])
    if len(frames) > 0:
        video_frames = torch.stack(frames, 0)

    return video_frames, video_pts, video_object.get_metadata()

We made our own configuration file for MineCLIP to avoid using Hydra and the weights were downloaded as pointed in the README file

MineCLIP config

arch: "vit_base_p16_fz.v2.t2"

In particular, in the craft-golden-pickaxe task there are subtasks like "find a place with lots of iron" and in the video GPT-golden-pickaxe video we do that but the reward never goes above ~0.3 despite the agent finding iron to mine.

---

However, we ran another experiment interacting with the environment instead of human gameplay with just the "find spider" prompt and using the delta-reward with mineCLIP and it was giving results that seemed more correct! So, we're seeing if the complexity of the GPT-generated sentences were why mineCLIP was not giving good rewards.

That being said, when we switched back to direct correlation as the reward we see the same results as the human videos:
