[Errno 2] No such file or directory: 'output.raw'

Hi, I am trying to use the library on some dji captured images but it's returning me this error:

Any thoughts?

Thank you.

@agarwalkunal12 - can you check this out?

[agarwalkunal12]

Hey @bksrocks , Could you please provide the following details:

1. What OS were you running this on and the architecture? (Windows/Linux and 32/64 bit?)

2. Can you verify that you had your internet connection working fine at the time of running the program? The DJI executables are downloaded the first time the program is run which create a file called 'output.raw'. If at the time of running the internet wasn't connected, it wouldn't have downloaded those executable files.

3. Also, those executables are downloaded as a zip file called 'dji_executables.zip' in the same location as your python script in which you import the library. Can you confirm once that the location where your python file exists contains a zip file called 'dji_executables.zip' or a folder by the name 'dji_executables'?

Thank You

Hi @agarwalkunal12 , thank you for responding!

1 - Windows 10 Enterprise, 64 bit

2 - Internet connection is fine. Is the .raw file downloaded to the folder in which I have my Jupiter notebook?

3 - Dji executables are in the folder.

Hi @bksrocks , thanks a lot for the information.

A couple of other users were getting a similar error and we figured that they were using the Mavic 2 Enterprise Advanced camera to capture the thermal images and the SDK didn't support that.

We have pushed a code update and it is supporting the Mavic 2 Enterprise Advanced cameras now too. Request you to refresh your codebase with the updated version and try and test it out. Let me know if the error still persists.

And if it does persist, request you to kindly upload the captured images that throw the error if they continue to do so.

Thanks Kunal

I bet that was the problem. It seems to be working now! Thank you very much!
