11. **自定义字典训练的模型,识别结果出现字典里没出现的字**
|
||||
预测时没有设置采用的自定义字典路径。设置方法是在预测时,通过增加输入参数rec_char_dict_path来设置。
|
||||
|
||||
12. **服务器CPU预测时内存一直涨**
|
||||
主要有由于开启了MKL数学库和多线程加速导致的问题,该问题我们已经在跟进修复。
|
||||
临时解决方案有两种:
|
||||
(1)注释掉数学库的使用,但是速度慢一倍,注释方法,https://github.com/PaddlePaddle/PaddleOCR/blob/develop/tools/infer/utility.py 文件中,注释掉94,95行

|
||||
|
||||
(2)定期释放和初始化TextSystem这个类,速度略微受影响。
|
||||
可以参考如下代码,修改 https://github.com/PaddlePaddle/PaddleOCR/blob/develop/tools/infer/predict_system.py 中main函数代码,
|
||||
|
||||
```
|
||||
def main(args):
|
||||
image_file_list = get_image_file_list(args.image_dir)
|
||||
text_sys = TextSystem(args)
|
||||
is_visualize = True
|
||||
count = 0
|
||||
for image_file in image_file_list:
|
||||
img = cv2.imread(image_file)
|
||||
if img is None:
|
||||
logger.info("error in loading image:{}".format(image_file))
|
||||
continue
|
||||
count += 1
|
||||
if count % 10 == 0:
|
||||
text_sys = TextSystem(args)
|
||||
starttime = time.time()
|
||||
dt_boxes, rec_res = text_sys(img)
|
||||
elapse = time.time() - starttime
|
||||
```
