gradCAM() unclear error message

Hi,

I am trying to use the gradCAM() function on my own data (attached).

when I run the following command;

map = gradCAM(net,features,label)
%Error ==> Network input layer must be an imageInputLayer or image3dInputLayer.

however the documentation clearly states a SequenceInputLayer can be used and gives an eample. I believe my net conforms to all input argument requirements and appears to input the same way as the SequenceInputLayer example.

What is causing this error?

Hi Christopher,

I have used the attached files and the code provided above. It works fine for me without any errors in R2022b. The "net" has met all the input argument requirements; I did not notice any flags.

Try clearing out the workspace and execute the code again.

clear;

Hope this helps!

Hi Sai,

Thank you for your response. I have now tested this both on R2022b and R2019b. As you mention on R2022b it runs without issue, however on R2019b there seems to be a bug.

This is unfortunate as I have access to an HPC which is currently running R2019b. However it atleast gives me a work around. Thank you for your help!
