我有一个 numpy 数组，它是形状（高度，宽度，3）的彩色图像“img”，也是形状（高度，宽度）的深度 numpy 数组。我想创建一个 RGBD 图像并显示它，为此我正在执行以下操作：

o3d.geometry.RGBDImage.create_from_color_and_depth(img, depth)

但我收到错误：

TypeError: create_from_color_and_depth(): incompatible function arguments. The following argument types are supported:
    1. (color: open3d.open3d_pybind.geometry.Image, depth: open3d.open3d_pybind.geometry.Image, depth_scale: float = 1000.0, depth_trunc: float = 3.0, convert_rgb_to_intensity: bool = True) -> open3d.open3d_pybind.geometry.RGBDImage

如何解决这个问题？如果需要Image类型，那么如何将numpy数组转换为Image类型？

即使我将 numpy 数组传递到 o3d.geometry.Image 构造函数中，如下所示：

o3d.geometry.RGBDImage.create_from_color_and_depth(o3d.geometry.Image(img), o3d.geometry.Image(depth))

我收到错误：

TypeError: create_from_color_and_depth(): incompatible function arguments. The following argument types are supported:
    1. (color: open3d.open3d_pybind.geometry.Image, depth: open3d.open3d_pybind.geometry.Image, depth_scale: float = 1000.0, depth_trunc: float = 3.0, convert_rgb_to_intensity: bool = True) -> open3d.open3d_pybind.geometry.RGBDImage

我想在连接到 Jetson Xavier nx 的 macOS 上启用 x11 转发。但是，连接后：

sudo ssh -Xvvv id@host

连接建立成功。但在详细日志中，我得到以下信息：

我想从aws s3存储下载整个存储桶“my-bucket”，并将其保存在路径“./resources/my-bucket”中。因此，我正在执行以下操作，导入 boto3，使用 access_key_id 和 Secret_access_key 创建资源，然后迭代存储桶中的所有对象并使用 download_file api 调用下载它们：

import boto3
s3 = boto3.resource(
service_name="s3",
region_name="us-west-1",
aws_access_key_id="AWUHWIEDFB",
aws_secret_access_key="AOIERJGOERWHJO"
)

for o in s3.Bucket("my-bucket").objects.all():
    filename = o.key
    s3.Bucket("my-bucket").download_file(Key=filename, Filename="./resources/my-bucket/" + filename)

s3 存储桶 my-bucket 本身有一个名为“input”的文件夹，其中仅包含 png 和 jpg 文件，并且根路径中还有另一个 .pt 文件。

但我收到错误：

FileNotFoundError: [Errno 2] No such file or directory: './resources/my-bucket/input/.F89bdcAc'

我不知道 .F89bdcAc 是什么意思，也不知道为什么 boto3 试图找到该文件。

我在 MongoDB 上有一个集合，我尝试使用以下方法从中查询所有元素find()：

const mongoose = require('mongoose');
const Featured = mongoose.model('featured');
module.exports = app => {
    app.get('/api/featured', async (req, res) => {
      console.log("featured route");
      const featured = await Featured.find();
      console.log(featured);
      res.send(featured);
    })
}

这是Featured.js：

const mongoose = require('mongoose');
const { Schema } = mongoose;

const featuredSchema = new Schema({});

mongoose.model('featured', featuredSchema);

但是，我在发出请求时收到错误：

(node:75568) UnhandledPromiseRejectionWarning: MongooseError: Operation `featureds.find()` buffering timed out after 10000ms
