【系统路径缺失】无法完成初始化，PaddleOCR-json.exe报错chcp不是内部或外部命令

[Oldsport-996]

您好 今天使用卡初始化了 不知道什么原因

[hiroi-sora]

请问以前使用是正常的吗？如果是，可能配置文件被修改过，而且参数不正确。尝试下载最新版软件，看看可否运行。

如果依然不行，尝试打开 PaddleOCR-json 文件夹下的识别引擎 PaddleOCR_json.exe ，看看它有无报错。如果有报错，则可能你的电脑安装（注册）了某些运行库与引擎产生了冲突。方便的话，把报错内容发上来。

作者大大您好 我在下载了1.2.6版本后也出现了初始化失败的问题
在读图后直接运行、选择识别区域、或者剪切板读取时都有同样的初始化失败报错
然后我运行了PaddleOCR_json.exe 并没有报错
最后我下回了1.2.5版本后还是可以使用的
我怀疑是 更新PaddleOCR-json模块至v1.2.0 之后有兼容问题？

@andongya95

可否将1.2.6初始化失败的弹窗截图放上来？我想看看它的信息

[Oldsport-996]

您好 他就是一直初始化，然后软件没什么反应

[hiroi-sora]

运行PaddleOCR_json.exe时，是不是打印一大串日志、最后显示 OCR init completed. ?

[Oldsport-996]

[Oldsport-996]

这个任务也没法停止，一直显示 正在停止，右键关闭还关闭不了，只能用任务管理器强制关闭软件

[hiroi-sora]

'chcp' 不是内部或外部命令

意料之外的问题。你电脑打开cmd，输入where chcp，看看会不会输出正确的路径？
如果没有，尝试将 C:\Windows\system32 加入系统路径
如果有，尝试将 PaddleOCR_json 文件夹加入系统路径
参考：https://blog.csdn.net/weixin_38314865/article/details/84594065

这个任务也没法停止，一直显示 正在停止

OK，以后会加入超时监控以防止程序因未知原因卡死

[Oldsport-996]

嗯 可以了 谢谢作者大大，我将C:\Windows\system32 加入系统路径 后 可以进行识别了

@hiroi-sora
我的PaddleOCR_json.exe运行后得到的是OCR init completed和图中一致
我也试了把文件夹加入系统路径，现在依然还是初始化失败的报错

[hiroi-sora]

@andongya95
是的，你的问题跟楼主不一样，与系统路径无关。可否在你机器上运行下述代码，看看有无问题

import os
import subprocess  # 进程，管道

# exePath = r"填入PaddleOCR_json.exe的路径"
exePath = r"D:\MyCode\PythonCode\Umi-OCR\PaddleOCR-json\PaddleOCR_json.exe"

cwd = os.path.abspath(os.path.join(exePath, os.pardir))
print(exePath, cwd)
popen = subprocess.Popen(  # 打开管道
    exePath, cwd=cwd,
    stdin=subprocess.PIPE,
    stdout=subprocess.PIPE,
)
for i in range(1000):
    if not popen.poll() == None:  # 子进程已退出，初始化失败
        print('子进程已退出，初始化失败！')
        break
    initStr = popen.stdout.readline().decode('ascii', errors='ignore')
    print(f'{i} : {initStr}')
    if 'OCR init completed.' in initStr:
        print(f'初始化成功！')
        break
    if i >= 999:
        print(f'输出条数异常，初始化失败！')
if popen.poll():
    popen.kill()

@hiroi-sora
我跑了之后卡在了第一次loop里
0 : Active code page: 65001
现在暂时还没动过

更新：
我发现是进程卡了
我重新跑了之后得到了
0 : Active code page: 65001
1 : OCR init completed.
初始化成功！

[hiroi-sora]

那既然这段demo能跑，Umi-OCR理应没问题呀

试试直接调用 callingOCR.py ，在最后加入一行

ocr = CallingOCR('填入PaddleOCR_json.exe的路径')

把第46行的initStr打印出来
把第49行的 # print(f'初始化OCR成功，进程号为{self.ret.pid}') 取消注释

看能不能初始化成功
