Hello,

I am trying to train my own object detection model : [https://github.com/dusty-nv/jetson-inference/blob/master/docs/pytorch-collect.md](https://github.com/dusty-nv/jetson-inference/blob/master/docs/pytorch-collect.md) and trying to collect own dataset.

When I run camera-capture, I get the following error:

> bash: camera-capture: command not found

PATH: `/jetson-inference/tools/camera-capture$`

I also removed this folder and cloned new folder from : [GitHub - dusty-nv/camera-capture: GUI tool for collecting & labeling data from live camera feed](https://github.com/dusty-nv/camera-capture.git) and ran cmake …/ and make.

But what jetson module you are using (Nano, TX2, etc.)? Also, what camera model do you have?  
Initially, those sample tutorials where done with a specific camera described in the link below. Do you have the same model?

Hi,

I am using Jetson TX2 which has on board MIPI CSI camera and running

> camera-capture

without any argument uses on-board camera as described in this tutorial.

Hi @arjunTX2, please run `sudo apt-get install qtbase5-dev` first. The camera-capture app will then be built. Normally this happens when you choose to install PyTorch during the cmake step.

Also, if you deleted the camera-capture dir from your local copy of the repo, you probably want to start fresh and re-clone to repo to properly build that tool.

Hi,  
I cannot load the “camera-capture” tool. I tried several locations (see the list below). I get the following error each time: **bash: camera-capture: command not found**

Locations tried:  
**ahalim@Xavier:~/jetson-inference/build/tools/camera-capture$ camera-capture**  
**ahalim@Xavier:~/jetson-inference/tools/camera-capture$ camera-capture**  
**ahalim@Xavier:~/jetson-inference/build/aarch64/bin$**  
**ahalim@Xavier:/usr/local/bin$**

I did install qtbase5-dev:  
**$ sudo apt-get install qtbase5-dev**  
**$ cd jetson-inference/build**  
**$ cmake …/**  
Linking jetson-inference with OpenCV 4.1.1  
– Configuring done  
– Generating done  
– Build files have been written to: /home/ahalim/jetson-inference/build  
**$ make**

After “make” I tried running from the following location again but to no avail:  
**ahalim@Xavier:~/jetson-inference/build/tools/camera-capture$ camera-capture**

I am running :

- JetPack 4.4 on Jetson Xavier NX
- Python 3.6.9 on linux
- torch version: 1.4.0a0+7f73f1d
- CUDA available: True

If possible kindly recommend a solution.

Hi @halimatif, try running the following commands:

```bash
$ cd jetson-inference/build
$ cmake ../
$ make

```

I think it should then build the tool for you (to `jetson-inference/build/aarch64/bin`)

Hi,  
I tried your recommendation but it did not work for me. Below I have listed all output. **Bold** lines are my commands. In the output, I did note the following:

I have Python 3.6.9 installed.

Hi @ahalim, it built `camera-capture`, you just need to run it as `./camera-capture` when you are in the same dir.

Otherwise you can do a `sudo make install` and then run it without the leading `./`

Thank you so much. I am sure this will work. Unfortunately my xavier does not want to reboot any more. Earlier today the system prompted me to install an available update. I opted to update. Now, on restart I just see a blank screen with a small cursor blinking on the top left corner of the screen. I now have to resolve this first. Perhaps I need to rebuild the system…

Hi @halimatif, you might want to see this post: [JetPack 4.4 - L4T R32.4.3 production release - #4 by suhash](https://forums.developer.nvidia.com/t/jetpack-4-4-l4t-r32-4-3-production-release/140869/4)

Hi,  
I had to re-image xavier (jetpack 4.4) to get it to reboot. Trying to set up for the Hello AI World lesson again.

In the section “Building the Project from Source”, after install Pytorch for Python 3.6, under the section below

Compiling the Project  
Make sure you are still in the jetson-inference/build directory, created above in step #3.  
Then run make followed by sudo make install to build the libraries, Python extension bindings, and code samples:

$ cd jetson-inference/build # omit if working directory is already build/ from above  
$ make  
$ sudo make install  
$ sudo ldconfig

When I execute the “make” command I get the following:  
ahalim@Xavier:~/jetson-inference/build$ make  
make: \*\*\* No targets specified and no makefile found. Stop.

This did not happen when i first tired it. Can you please help.  
Regards

First, you probably want to run `sudo apt-get install qtbase5-dev` again.

Then, did you run `cmake ../` from the build dir before running `make`? Normally if it says ‘no makefile found’, it was because cmake hadn’t been run yet.

Hi,  
Executing the cmake …/ worked. Thank you. I can not run the Hello AI World tutorial. Since the Jetpack 4.4 update yesterday, I noticed that opencv face\_recognition has become extremely slow. I don’t think the GPUs are working at all in this case now. Can you comment on this?

Glad that you got the camera-capture to build - what part of Hello AI World can’t you run? Or did you mean you can now run it.

By default OpenCV is not build with GPU acceleration. Had you previously installed a custom build of it? I recommend you file a new topic about the issue since this topic was about something different - thanks!
