Cannot reproduce results of "coordconv_rendering" task

[hubert0527]

I get zero accuracies by running the instructed command:

# coordconv version
python train.py --arch coordconv_rendering -mb 16 -E 100 -L 0.005 --opt adam --l2 0.001 -mul 1 --use_mse_loss

I am using the instructed tensorflow 1.14 environment as well.
Since there are obvious runtime errors (e.g., variable not declared here and here), I suspect the codes are released without even testing if the codes runnable (not to mention the numbers in the paper).

Can the authors make some clarifications on what is the status of this repo?
