Pre-train Model

[r0438930]

Dear,

After running make.exe to compile the Makefile, this generates the magic.exe.

Next I try to run 'python prepare_pretrain_embedding.py' which recognizes the subprocess.call('magic -i ...) but calling
subprocess.call('python format_transform.py ...) gives me the below error. I realize that com-amazon_final.f.txt is not found but what is this file and how do I generate it? Is this the output of the subprocess.call('magic ...)?

Since I am trying to run CommunityGAN on different datasets I really hope to find a solution.

ERROR MESSAGE:
Traceback (most recent call last):
File "format_transform.py", line 13, in
with open(bigclam_out_filename) as fp, open(output_filename, 'w') as out_fp:
FileNotFoundError: [Errno 2] No such file or directory: '../src/PreTrain/community_detection/com-amazon_final.f.txt'

Sincerely,

Simon

Hi Simon,

The file '../src/PreTrain/community_detection/com-amazon_final.f.txt' should be generated by the pretrain model MAGIC, which is the trained embeeding file of MAGIC.
line 9 (subprocess.call('python format_transform.py ...)) will read the file and transform the format for communityGAN.
If you want to run on some different datasets, you should edit the prepare_pretrain_embedding.py and replace the corresponding filenames in line 8-9.
Moreover, you can comment line 10-13, which is the pretrain process for the given dataset youtube and dblp.

Best regards,
Yuting Jia

Dear Yuting,

Thanks for the fast reply!

The real problem is that when I run magic, the "..._final.f.txt" file is not generated! I made sure that I gave the right input AGM file. I have tried it with all three included datasets but I do not see any files being generated. Therefore format_transform.py is not really the problem, I just dont see magic generating that txt file.

I fear that it may have something to do with how the magic.exe file is generated. I installed MinGW as mentioned in the readme file. I opened the PreTrain directory in powershell and ran the "make" command which generated all the ".o" files as well as magic.exe. Next I return to python to run prepare_pretrain_embedding.py given the correct -i and -o arguments. The code runs but no "...final.f.txt" file is generated.

When I run subprocess.call(magic ...) I do not get any errors (exit code 0). I see the below post when running magic. Note for -o I tried to generate file directly in PreTrain directory and for -i I placed the agm file in the PreTrain directory as well.

Hopefully this makes my problem more concrete. Obviously making a minimum reproducible code sample is not really possible here.

Do you have any suggestions to get "...final.f.txt" to be generated?

Thanks in advance,

UPDATE:

By running magic.exe directly into windows powershell, the code is fully executed.
There seems to be a problem with 'subprocess.call()' here where it does not fully execute magic.exe.
I do not know the exact issue but this resolved it for me and all .txt files were generated!

Hopefully this helpes anyone with a similar issue in the future!

Sir how do you download Magic.exe file?
Can you please provide me link. I can not find it anywhere
