Thank you very much for your excellent contribution.
I downloaded the code in October 2019.
system:windows1803
Graphics card:1080Ti
tensorflow-gpu :1.4.0 (I'm using cuda8.0, but 1.4.0 released in November 2017. I think it's ok)
tensorflow-tensorboard :0.4.0
model:icnet_cityscapes_trainval_90k.npy(frome google driver)
I just open demo.ipynb by using jupyter and change nothing. It ran successfully and got the right results. But when I use the code as below:
for i in range(50):
start_t = time.time()
_ = net.predict(im1)
duration = time.time() - start_t
if i > 0:
elapsed_times.append(duration)
I got "Average time: 0.1461, about 6.843729 fps". It seems like that the inference time is too high(should be ~0.04s).
First, I thought the function "time.time()" maybe different between win and linux. I ruled out this later.
Then, I find some issue mentioned that maybe the first image inference time is right and the others are not. So I add print duration below duration = time.time() - start_t. Disappointingly, first picture is about 1.24 s and the others are around 0.14 s.
But I find something that seem to effect. The information print in the cmd shows that:
Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX AVX2
They all say that it is because the tensorflow version is too low. But I think it may not matter with speed. At least tensorflow-gpu 1.4.0 is appropriate in terms of time.
If there is an omission, the message is not posted. Please understand.
