The Model is unstable

After training my own dataset, the model began to become unstable. The effect after visualization as shown:The output of d and d_ begins collapse after the 8 epochs.
Excuse me, what is the cause of this?

Start by reproducing the report with the author's own dataset and the training setup used for DCGAN-tensorflow. Inspect the visualization of d and d_ around epoch 8 and compare it with a known-good training run. Done requires identifying a reproducible cause of the instability and documenting a verified fix or configuration change.
