Got [name 'decode' is not defined] error on MacOS/RasbianOS #14

When running python app.py

I got similar error for both flask apps(object counting/traffic counting):

Searched other places, no good, seems not general issue.

I'm using: Tensorflow 1.14 Keras 2.3.1 opencv-python 4.2.0 ImageZMQ numpy 1.18.2 Flask 1.1.1 pillow

on a MacBook(10.15.5), also tried RasbianOS, both got above error.

Python version I'm using is 3.7.2, the recommended is 3.6, not sure if this is the key.

Thanks.

I just setup the evironment with a Jetson Nano(similar OS with Raspbian), this time python3.6 is used with tensorflow-gpu 1.15.

however, no good. the same reason.

I tried it on Win10 but cannot run it for the same reason.

It doesn't work for the same reason

bqFirst commented 4 years ago

I run it successfully! First, make sure that the yolov4.weights is loaded correctly. Second, make sure that the model_image_size in the yolov4.py is the same as yolov4.weights
