[Bug] Train a personalized DeepFloyd model by DreamBooth Lora. Execute stage 1, but there is no personalized effect

Great job.
You mentioned Train a personalized DeepFloyd model by DreamBooth Lora. I followed the relevant instructions to train a lora weight, and then executed stage 1, but there is no personalized effect, that is to say, it did not generate content related to my topic. Why is this?

The command to train lora is as follows

export MODEL_NAME="DeepFloyd/IF-I-XL-v1.0"
export INSTANCE_DIR=".cache/temp"
export OUTPUT_DIR=".cache/if_dreambooth_mushroom"

accelerate launch threestudio/scripts/train_dreambooth_lora.py \
  --pretrained_model_name_or_path=$MODEL_NAME  \
  --instance_data_dir=$INSTANCE_DIR \
  --output_dir=$OUTPUT_DIR \
  --instance_prompt="a sks mushroom" \
  --resolution=64 \
  --train_batch_size=4 \
  --gradient_accumulation_steps=1 \
  --learning_rate=5e-6 \
  --scale_lr \
  --max_train_steps=1200 \
  --checkpointing_steps=600 \
  --pre_compute_text_embeddings \
  --tokenizer_max_length=77 \
  --text_encoder_use_attention_mask

The command to train stage 1 is as follows

# --------- Stage 1 (NeRF & NeuS) --------- # 
python launch.py --config configs/dreamcraft3d-coarse-nerf.yaml --train system.prompt_processor.prompt="$prompt" data.image_path="$image_path" system.guidance.lora_weights_path=".cache/if_dreambooth_mushroom"
