FileNotFoundError while deploying Flask Rest API

[Sarwagya_Agarwal]

I have been trying to deploy a REST API (POST) made in Flask (Python). The API basically takes X-Ray Images as input and then outputs whether it is infected by pneumonia or not. For carrying out this task, I have used the pickle file of a previously trained model, but due to some reason while deploying the API it’s showing some kind of error.

Here is my Github Repo Link. Kindly let me know if I need to add or delete anything.

The log has been attached below -

Hey,

Your code is searching for a file in the “/tmp” folder, but it appears that the file does not exist. I’m uncertain whether it should be located at the root of your repository or the root of the filesystem. However, in either case, the file is not present during the build process. To resolve this, please ensure that the necessary files are placed in the correct location before deployment.

Furthermore, it seems that you are deploying and/or utilizing an ML model. It’s important to note that such applications typically require a paid instance with higher CPU and RAM resources allocated. These resources are crucial for the efficient operation of ML models. Therefore, it is recommended to consider using a paid instance to adequately provision the required CPU and RAM for optimal performance.
