How do I use the model with my own image stream and pose data?
I think I might be over complicating the process, but here is what I tried so far:
I have tried calling the Neural_SLAM_Module() alone first to test out using my own images, but I can't seem to get that to work let alone the other models for exploration.
test.py file:
from model import RL_Policy, Local_IL_Policy, Neural_SLAM_Module
from PIL import Image
import torch
import numpy as np
from arguments import get_args
device = torch.device("cuda:0")
map_size_cm = 1000
map_resolution_cm = 5
map_size = map_size_cm // map_resolution_cm
full_w, full_h = map_size, map_size
local_w, local_h = full_w // 4, full_h // 4
# Initializing full and local map
full_map = torch.zeros(1, 4, full_w, full_h).float().to(device)
local_map = torch.zeros(1, 4, local_w, local_h).float().to(device)
# Initial full and local pose
full_pose = torch.zeros(1, 3).float().to(device)
local_pose = poses = torch.zeros(1, 3).float().to(device)
img = Image.open("test_img.jpg")
img = np.transpose(img, (2, 0, 1))
obs = torch.from_numpy(np.transpose(np.expand_dims(img, axis=0), (0, 1, 3, 2))).float().to(device)
last_obs = obs
print(obs.size()) # (1,3,128,128)
args = get_args()
args.device = device
args.frame_height = 128 # image height
args.frame_width = 128 # image height
args.map_resolution = map_resolution_cm
args.map_size_cm = map_size
nslam_module = Neural_SLAM_Module(args).to(device)
_, _, local_map[:, 0, :, :], local_map[:, 1, :, :], _, local_pose = \
nslam_module(last_obs, obs, poses, local_map[:, 0, :, :],
local_map[:, 1, :, :], local_pose, build_maps=True)
This gives me the following error:
/home/.../Desktop/Neural-SLAM/test.py:27: UserWarning: The given NumPy array is not writable, and PyTorch does not support non-writable tensors. This means writing to this tensor will result in undefined behavior. You may want to copy the array to protect its data or make it writable before converting it to a tensor. This type of warning will be suppressed for the rest of this program. (Triggered internally at /opt/conda/conda-bld/pytorch_1678402411778/work/torch/csrc/utils/tensor_numpy.cpp:206.)
