dji | 大疆无人机开发 路径功能 DJI Mobile SDK Waypoint | SDK library

My first attempt to generate this type of file, not very familiar, please help me. I want to achieve the following effect

I'm currently working on a Tkinter GUI for my DJI Tello, and I'm trying to make it so that when I command the drone to takeoff/land, the streamed video on the GUI does not freeze. I'm not too familiar with multithreading, but I looked the issue up and it seems like I'm not the only one encountering this. So I used what I found regarding threading and starting threads, and ended up with this line (more or less):

(Mobile SDK) I get 'Error- the GPS Signal of the aircraft is weak(216)' when I try to start a FollowMe mission while using the simulator i.e. on the line FollowMeMissionOp.startMission(followMeInitSettings, new CommonCallbacks.CompletionCallback()... where FollowMeMissionOp = DJISDKManager.getInstance().getMissionControl().getFollowMeMissionOperator();

I'm using the code at Custom Follow Me Mission DJI Android SDK as my template, but the bulk of the code is irrelevant here as the error is thrown at the start.

I'm starting the simulator within the program... mFlightController.getSimulator().start(InitializationData.createInstance(CenterScreen, 10, 10), new StartSimulatorCallback());

The simulator is working well for other types of missions- Waypoint, Timeline- with various actions, and indeed simple joystick control- there's quite a few things in the program at this stage that have tested it.

I cannot see anything different about using it for the FollowMeMissionOperator, so I'm inclined to think its a bug.

Can anyone throw any light on the issue?

(As a further footnote, it all works fine if I use the simulator in DJI Assistant instead of starting it with an SDK command)

Upon running nvidia-smi through terminal, i am met with nvidia-smi command not found However, i am aware that jetpack 3.3 (the nvidia drivers) have already been installed. Has anyone encountered similar problems with Nvidia jetson tx2 ?

I have a dataset with about 50 columns (all indicators I got from World Bank), Country Code and Year. These 50 columns are not all complete, and I would like to fill in the missing values based on an lm fit for the column for that specific country. For example:

Doing this for a single country and a single column is absolutely fine when following these steps here: Filling NA using linear regression in R

However, I have over 180 different countries I want to do this to. And I want this to work for each indicator per country (so 50 columns total) So in a way, each country and each column would have its own linear regression model that fills out the missing values.

Here is how it looked after I did the steps above: This is the expected output for ONE column. I would like to do this for EVERY column by individual country groups.

However, the data looks like this:

There are numerous countries and columns that I want to perform this on just like the post above.

This is for a project I am working on for my data-mining / statistics class. Any help would be appreciated and thanks so much in advance!

EDIT

I tried this:

I am trying to use an Nvidia Jetson Nano as an onboard computer to communicate with the Matrice 300 RTK using the OSDK. The computer and drone are connected using the OSDK Expansion module, and I am using the dual USB cable (USB 3 Type A) to connect to a USB port on the computer.

I am getting the error

I am trying out the DJI SDK and am following this tutorial on how to integrate the SDK into the Android Studio project I have created. I've replicated everything down to the name of the files, with the only difference being that I added the needed import statements in MainActivity.java.

I get the following error when I try to build the project:

I am trying to run this github repo found at this link: https://github.com/HowieMa/DeepSORT_YOLOv5_Pytorch After installing the requirements via pip install -r requirements.txt. I am running this in a python 3.8 virtual environment, on a dji manifold 2g which runs on an Nvidia jetson tx2.

The following is the terminal output.

I have gotten these consecutive errors, despite having properly installed the required dev libs and the venv lib.

here is the consecutive output in terminal.
