Random search crash at the end? due to NaN ? on classifier.fit(..)

[nevermindthat]

Hi,

Thanks for the great paper and code!.

1. I'm trying to reproduce your results for census and covertype datasets, i wasn't able with the out of the box settings, so i tried your random search but ran into this issue.
   This issue is about that.

2. I would love to know your parameters settings for census data and covertype.
   As they weren't mentioned.

3. Also where can i find the preprocessing code for these datasets as the given ones
   http://hdi-project-tgan.s3.amazonaws.com/index.html
   Have already been processed. There's also no test split - where can i find it? it's not in the link provided.
   The section: https://dai-lab.github.io/TGAN/readme.html#input-format
   Only say:

The input data for this fitting process has to be a single table that satisfies the following rules:
Has no missing values.
Has columns of types int, float, str or bool.
Each column contains data of only one type.

How did you impute data if was missing? what scaling you've used, etc.. as i'm trying to reproduce.

4. I didn't see the discriminator converges to "fake accuracy" 0.5 and "real accuracy" 0.5 at any of my runs. How come? tried to read here in issues, the papers, code.. how come?

Description

I've ran
tgan experiments config_hpo.json results.jsons
This was the outcome:

What I Did

config_hpo.json looks:

Seems this is the line that raises the error because of NaN ?

Thank you!

@nevermindthat how did you make "tgan experiments config_hpo.json results.jsons" line work? For me it just says invalid syntax. what was your code before this line? I will just add my code below, please let me know what changes i need to make.

!git clone https://github.com/sdv-dev/TGAN.git

cd TGAN

!make install-develop

!pip uninstall tensorflow
!pip install "tensorflow-gpu>=1.13.0,<2.0"

import pandas as pd
data = pd.read_csv("dataset_linux_driver_net_new.csv") #I am using my own dataset

continuous_columns = [x for x in range(83)] #It has 83 continuous columns
continuous_columns

from tgan.model import TGANModel
tgan = TGANModel(continuous_columns)

tgan experiments config.json results.json #config.json exists in the main TGAN directory & not under examples
