I have a problem with using "alexnet" trained net

>> load(alexnet) Error using load Unable to read data stream because the data contains a bad version or endian-key

Error in alexnet (line 56) data = load(matfile);

what is that error meaning !!

[Walter Roberson]

net = alexnet;

Do not load() the results of running alexnet.

Might be able to tell you more about what is in the matfile. You would need to

dbstop on error

and run the code and look at the matfile variable to find out where the matfile is stored.

Even i am facing the same problem.

>> net = alexnet
Error using load
Cannot read file
C:\ProgramData\MATLAB\SupportPackages\R2019a\toolbox\nnet\supportpackages\alexnet\data\alexnet.mat.

Error in alexnet (line 56)
        data    = load (matfile);

Did you happen to try the corruption tool that I have suggested?

[Hanna Vanessa R. Simulata]

Hi,

I have the same issue as Aziza. I m using matlab2019b, windows 64bit, RAM = 32GB.

I run the file corruption tool ( https://www.mathworks.com/matlabcentral/fileexchange/6893-matcat-mat-file-corruption-analysis-tool ) and it was successful. So the mat file is not corrupted.

Any Idea how to fix this problem?

[Walter Roberson]

Hanna, are you getting the message about bad version or endian key as well, or is it just saying that it cannot read the file, or is it saying failure to load ?

[Hanna Vanessa R. Simulata]

yes, I do have the message about bad version or endian key as well.

Try re-installing the support package for Alexnet.

The alexnet.mat file that gets installed is currently 227421769 bytes.
