完美解决丨RuntimeError: create_session() called before __init__().

错误：

import sys

sys.path.append('/home/pi/ssd-detect')

import ssd_detect

ssd_detect.detect('/home/pi/ssd-detect/test.jpg')

报错如下：

Traceback (most recent call last):

File "test.py", line 6, in <module

ssd_detect.detect('/home/pi/ssd-detect/test.jpg')

File "/home/pi/ssd-detect/ssd_detect.py", line 31, in detect

output_dict = run_inference_for_single_image(image_np, detection_graph)

File "/home/pi/ssd-detect/ssd_detect.py", line 15, in run_inference_for_single_image

原因分析：

根据错误的描述，也就是说调用了 sess.run() 这个函数之前没有初始化 sess ，这样就会报错。

这个错误是因为 sess.run() 这个函数是在 sess 被初始化之后才能被调用。
