Problem with data_integration file

[kokosowygosc]

I get fallowing error during data integration process:

File "data_integration.py", line 55, in <module> model=load_model('autoencoder.h5',custom_objects={'corr2_mse_loss': corr2_mse_loss})
...
IOError: Unable to open file (unable to open file: name = #'autoencoder.h5', errno = 2, error message = 'No such file or directory', flags = 0, o_flags = 0)

It seems that there is no autoencoder.h5 file. Where I will find it?
All the previous steps of preparation went well with few changes. Please help me with this.
