ValueError: bad marshal data (unknown type code)

[muthiyanbhushan]

I converted the jupyter notebook "Embedding_Space_Visualisation.ipynb" to the python script and I was running using the Python3 environment with Cuda-10.1 installed on my laptop.

I am getting a ValueError: bad marshal data (unknown type code)

Traceback (most recent call last):

Can you please help me with the error?
Every help will be appreciated.
Thank you.

Hi @muthiyanbhushan and @oscarknagg ,

I am also trying to use this code for my research as part of a model I am trying to implement.

The error above started from;
File "Embedding_Space_Visualisation.py", line 38, in
siamese = load_model(model_path)

In my case I changed the cell above the load_model cell to

model_path = '../models/n_seconds/siamese__nseconds_3.0__filters_32__embed_64__drop_0.05__r_0.hdf5'

and downloaded the model file from
https://github.com/oscarknagg/voicemap/tree/master/models/n_seconds

I save the downloaded file to "../models/n_seconds/" and I was able to run that line 38 without a problem. If you haven't tried the above, please try it to see if it works for you.

Further cells down, I am getting an error on the cell with:

Z = [train[i] for i in np.random.randint(0,len(train),size=n_samples)],

train is a class object, so I am still trying to figure out the indexing part.

Thanks,
Andrew

Hi Andrew,

Thank you for your help.
But, I am still not able to solve the error?

234 except (UnicodeEncodeError, binascii.Error, ValueError):

Is it because of my python version?
Thank you.
