AttributeError: 'module' object has no attribute 'attribute'

[fpgasdr]

Hi,
running some of the examples located in apps folder I get errors with the Attributes passed to the modules.
I don't know if this is an error related with my gnuradio enviroment or with gr-dpd. due in the net there is similar error with different solutons but none of them work for me.
Thanks,
regards.

Can you let me know exactly what attribute is listed as missing?

Hi @SrikanthPagadarai thanks for reply,
the problems of missing attributes are in blocks located in apps folder, who are the examples I'm trying to run.
for example:

• run_dpd_simulation_wienerPA_training.grc -> AttributeError: 'module' object has no attribute 'stream_to_message'
• run_dpd_simulation_wienerPA.grc.grc -> AttributeError: 'module' object has no attribute 'vector_vector_multiply'.
• save_dpd_training_input_physical_PA_tests.grc -> AttributeError: 'module' object has no attribute 'stream_to_gmp_vector'
• save_predistorted_input_physical_PA.grc -> AttributeError: 'module' object has no attribute 'vector_vector_multiply'.
• run_dpd_physical_PA_training.grc and tune_peak_value_estimate_int_delay.grc-> AttributeError: 'module' object has no attribute 'signum_func'

But the parameters are there and if I try to replace the parameters with the values it's the same error.
looking for this error in google normally is due the swig is not installed but in my case is installed but don't know if it's found by gnuradio.
I have this problem in 2 different computers with different setup.

digging into the code seems like the dpd class is imported but not correctly:
self.dpd_vector_vector_multiply_0 = dpd.vector_vector_multiply.
AttributeError: "'module' object has no attribute 'vector_vector_multiply'"
