Hi I am not getting 401 error but 400 client error: Bad request for url

https://westcentralus.api.cognitive.microsoft.com/vision/v2.0/recognizeText?mode=Handwritten

Do you have troubleshooting guide for it ?

[vashish76]

@YutongTie-MSFT - Now I am receiving the following error after inputting right key for subscription key

HTTPError: 404 Client Error: Resource Not Found for url: https://westcentralus.api.cognitive.microsoft.com/vision/v1.0recognizeText?mode=Handwritten

Does it mean that the end point url is not accessible ? I have this endpoint mentioned in keys section

Plz suggest

@vashish76 Hi, I have followed the tutorials and it works for me. And you should use V2.0 API version.

You can run this quickstart in a step-by step fashion using a Jupyter notebook on MyBinder according to the document: https://docs.microsoft.com/en-us/azure/cognitive-services/Computer-vision/quickstarts/python-hand-text

[vashish76]

HI YutongTie - I followed the quickstart and executed the code using Jupyter notebook but still i am receiving "Bad Request for url". I am pretty sure that something is wrong with the local image that i am trying to pass to the requests.post.

Please can you check the below code and advise where I am going wrong ? Appreciate your help

[vashish76]

@YutongTie-MSFT - Please help me in identifying the issue in the above code

[YutongTie-MSFT]

@vashish76 Sorry for the delay. For now, we don't support local image. You need to upload the image. Thanks.

[areed145]

@YutongTie-MSFT has local image support been enabled? If not, what are the plans/timing? Thanks!
