Traceback (most recent call last):

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

There is a error. I've tried several versions of mapper but it still failed. What is the proper and correct version of mapper?

The same question I meet.Directly,I have downloaded the dataset "2016.10b.dat" and It's to big to open.I just want to see the python code to find the format of the dataset.

I am also seeing this run time error. I have the dataset but I want to change the way its generated. Help please!

[kwmcclintick]

there appears to be a mapper made by tim o'shea
https://github.com/gr-vt/gr-mapper/tree/master/python

and this other one made by a Daniel Mullner
http://danifold.net/mapper/
...Daniel's is called when I type "import mapper" as v0.1.17, i downloaded it using pip

Ok yes I was right. to download gr-mapper (THE RIGHT ONE! :) ), type the following in the same location as your generate_RML2016.10a.py file and transmitters.py file

sudo git clone https://github.com/gr-vt/gr-mapper.git

cd gr-mapper

sudo mkdir build

cd build

sudo cmake ..

sudo make

sudo make install

sudo ldconfig

then exit your gr-mapper directory and type:

python generate_RML2016.10a.py
and you should be good! Not sure if you need all those sudo's, but I did.

Thanks for your detailed instruction, I've solved this on Linux system. Happy Spring Festival !

This procedure does not work on MacOS. Says No module named mapper. Any suggestions?

[hongdehua]

You should install gr-mapper library when error is " No module named mapper".

I've not tried on MacOs.

I am wondering if there is a gr-mapper version for GNU radio3.8, the gr-mapper uploaded from the URL as you showed is an old version which is not applicable. Thanks a lot!

gr-vt/gr-mapper#20 - this PR makes it compatible with GNU Radio 3.8

[sumit429]

Still my problem is not resolved.

[roman-popenov]

Still my problem is not resolved.

Have you tried porting the code from gr-vt/gr-mapper#20, it solved the issue for 3.8 only, but it might be compatible with other versions.

[sumit429]

Yes sir, I also tried porting the code from gr-vt/gr-mapper#20. I also have gnuradio version 3.8. ᐧ
