error decoding file

When I run generate_RML2016.10a.py, this error come out:

$ ./generate_RML2016.10a.py
snr is -20
len(interp_taps) = 287

Is there something that my computer missed?

By the way, it seems that the RML2016.10a_dict.dat has also been generated successfully. The .dat file size is 640.9MB.

When I run generate_RML2016.10a.py, this error is above.
Is there something about GNU that I need install?

您好，想咨询一下您，为什么我这边直接运行这个文件夹的代码，会一直提醒少各种库呢？是不是哪里还有一个GNU的库需要安装？

[ziyuanjun]

The error is related to SWIG, you can try to install it alone.
And maybe your GNU Radio has not been installed correctly. I use GNU Radio in linux, I'm not sure whether Win is a good choice.

I'm having the same problem.
It feels like there's something wrong with libav.
I have tried to reinstall gr-mediatools, but the problem still exists.

@ziyuanjun I'm having the same problem, have you solve this issue?
I have not got RML2016.10a_dict.dat generated. A "Segmentation fault" error is encounted!

this is a gnu radio problem

[pachpandepriti]

Can you mention the steps you followed to install gr mediatools? I am not able to do that.

@osh how can this issue be solved? Is the issue related to gr-mediatools?

Using pybombs install SWIG???

Can you mention the steps you followed to install gr mediatools? I am not able to do that.

I followed two steps in here and fixed the issue:

sudo apt-get install libavcodec-dev libavformat-dev

followed by making the change mentioned in the link below...
