can someone help with this error ?

paddlepaddle version?

[swap453]

2.6.1

[GreatV]

maybe you can refer: #8607

Thanks I will take a look at it

It's a problem with flask and paddlepaddle(cpu version).It can be solved using fastapi or paddlepaddle-gpu.Personally, it is recommended to replace flask with fastapi, because flask+paddlepaddle-gpu will cause the problem of gpu memory overflow.

@hardstone1998 where exactly we have to replace it with fastapi, can you please provide the code snippet

[hardstone1998]

This is my code demo. Fastapi can be used to run multiple times, but flask cannot

Use flask:
class TempPaddleOcr:
def init(self):
self.table_engine_en = PPStructure(recovery=True, lang='en', structure_version="PP-StructureV2",
enable_mkldnn=False, use_gpu=True)
tempPaddleOcr = TempPaddleOcr()
@app.route('/image2text', methods=['POST'])
def image2text():
file = request.files.get('file')
filename = str(uuid.uuid1()) + "." + file.filename.split('.')[-1]
if file:
file.save(upload_folder + filename)
img_path = upload_folder + filename
img = cv2.imread(img_path)
result = tempPaddleOcr.table_engine_en(img)
return {'code': 200}
if name == "main":
print("服务被启动")
app.run(host='0.0.0.0', port=8888)

Using fastapi:
class TempPaddleOcr:
def init(self):
self.table_engine_en = PPStructure(recovery=True, lang='en', structure_version="PP-StructureV2",
enable_mkldnn=False, use_gpu=True)
tempPaddleOcr = TempPaddleOcr()
@app.post('/image2text')
async def image2text(file: UploadFile = File(...)):
filename = str(uuid.uuid1()) + "." + file.filename.split('.')[-1]
file_path = upload_folder + filename
with open(file_path, "wb") as buffer:
content = await file.read()
buffer.write(content)
img_path = upload_folder + filename
img = cv2.imread(img_path)
result = tempPaddleOcr.table_engine_en(img)
return {'code': 200}
if name == "main":
print("服务被启动")
uvicorn.run(app, host='0.0.0.0', port=8888)

Thank you. I will try that

[rttariverdi67]

the problem occures when you define ocr= PaddleOCR() once and use it multiple times.

you should use it in a way that when you wanna call ocr you shoud redefine it.

I used the "lang" parameter when using it, and this error did not occur. example:
original: table_engine = PPStructure(show_log=True) Error
now: table_engine = PPStructure(show_log=True, lang='ch') never Error
