facenet on coral dev board - tensorflow

I ran facenet model on my computer and got good results. But when I ran the same model on coral dev board , the results are not as expected.
facenet on my computer - detects accurately,
facenet on coral dev board - very bad results.
Why is it behaving so different?
Note : using coral camera on dev board and webcam on computer.

YOLOv4-deepsort does not detect while running on Google Colab's GPU

I'm trying to do some object tracking on a video using Google Colab but I'm facing the issue below. Tracking is only done in the first frame of the video and not in the rest. I'm working with exactly same files and same commands both on my computer and Google Colab.

Google Colab

It seems like TensorFlow's version caused this problem. Here is my solution:
!pip install tensorflow==2.3.0

Installing ncnn on Google Colab

I have trained a custom YOLOX model on google colab and want to convert it from .onnx to .ncnn.
I'm using the following as directions: https://github.com/Megvii-BaseDetection/YOLOX/blob/main/demo/ncnn/cpp/README.md#step4
Step 1 requires building ncnn with directions: https://github.com/Tencent/ncnn/wiki/how-to-build#build-for-macos
The directions give instructions for building on different devices.
My question: Which instructions should I use to build ncnn on Google Colab?

Make Android Emulator use physical usb camera

Android Studio, latest Google SDK emulator. I have set back camera emulation mode to Webcam0 to get my usb camera connected to emulator. Unfortunately, it's not working. My camera works without any problems on host computer, for example this:
ffplay /dev/video0
gives me camera video playback. When I run emulator with above settings, camera on emulator just says "Unable connect to camera", then closes itself. Have anybody ever succeded with connecting physical camera to Android emulator? I have found some similar problems out there, but none of them has been resolved.

you can try to edit the config.ini of the AVD in ~/.android/avd/avd_name/config.ini like in this link http://viralpatel.net/blogs/enable-camera-in-android-emulator/ or use Android Studio directly like in this Android: How to use webcam in emulator?
if this isn't working see Lekensteyn's answer (2nd) in Connect USB device to Android Emulator?. it describes how a USB device can be passed through to a QEMU emulator. Android emulator is modified QEMU for more details see https://developer.android.com/studio/run/emulator-commandline.html
to find out if your webcam is recognized anyway try emulator #avd_name -webcam-list to get the available AVD use android list avd
