#### forward[[diffusers.models.StableCascadeUNet.forward]]

```python
forward(sample, timestep_ratio, clip_text_pooled, clip_text = None, clip_img = None, effnet = None, pixels = None, sca = None, crp = None, return_dict = True)
```

**Parameter:**

sample (`torch.Tensor`) : Sampel input berisik.

timestep_ratio (`torch.Tensor`) : Rasio timestep yang digunakan untuk menghitung embedding timestep.

clip_text_pooled (`torch.Tensor`) : Embedding teks CLIP yang dipool.

clip_text (`torch.Tensor`, *opsional*) : Embedding teks CLIP tingkat urutan.

clip_img (`torch.Tensor`, *opsional*) : embedding gambar CLIP.

effnet (`torch.Tensor`, *opsional*) : Peta fitur EfficientNet yang digunakan sebagai kondisioning tambahan.

pixels (`torch.Tensor`, *opsional*) : Tensor kondisioning tingkat piksel. Jika `None`, tensor berisi nol akan digunakan.

sca (`torch.Tensor`, *opsional*) : Nilai kondisioning `sca` opsional yang digunakan untuk membangun embedding timestep.

crp (`torch.Tensor`, *opsional*) : Nilai kondisioning `crp` opsional yang digunakan untuk membangun embedding timestep.

return_dict (`bool`, *opsional*, defaultnya `True`) : Apakah akan mengembalikan `StableCascadeUNetOutput` alih-alih tuple biasa.

**Mengembalikan:**

Jika `return_dict` bernilai True, sebuah `StableCascadeUNetOutput` akan dikembalikan, selain itu sebuah `tuple` di mana elemen pertama adalah tensor sampel.
