预训练模型做分子性质微调时，哪些参数应与预训练模型保持一致，哪些参数可以根据新任务自行设置。 + +## 1. 总体原则 + +预训练微调可以理解为： + +```text +DPA3 descriptor 使用预训练模型权重 +property fitting net / property head 面向新性质重新训练 +``` + +因此参数可以分成两类： + +```text +模型结构参数：应尽量和预训练模型一致，否则权重加载会失败 +训练任务参数：可以按当前数据和任务重新设置 +``` + +在当前 `deepmd_property_tools` 中，推荐使用： + +```python +PropertyTrain( + ..., + finetune=PRETRAINED_MODEL, + use_pretrain_script=True, +) +``` + +其中 `use_pretrain_script=True` 会让 DeePMD-kit 根据预训练模型里的 `model_params` 自动修正当前 `input.json` 中的模型结构，使其更容易和 `DPA-3.2-5M.pt` 对齐。 + +--- + +## 2. 应与预训练模型保持一致的参数 + +这些参数通常决定模型权重张量的形状或模型 forward 逻辑。如果和预训练模型不一致，容易出现： + +```text +size mismatch +missing key +unexpected key +``` + +### 2.1 `model.type_map` + +示例： + +```json +"type_map": ["H", "C", "N", "O"] +``` + +微调数据中的元素类型应被预训练模型支持。当前 20 条 demo 数据自动生成： + +```json +["H", "C", "N", "O"] +``` + +如果使用全量数据且包含 `I`，则可能生成： + +```json +["H", "C", "N", "O", "I"] +``` + +需要确认预训练模型支持这些元素。 + +### 2.2 `model.descriptor.type` + +必须是： + +```json +"type": "dpa3" +``` + +因为微调目标是继承 DPA3 descriptor。 + +### 2.3 DPA3 repflow 维度参数 + +这些参数应与预训练模型一致： + +```json +"n_dim": 128, +"e_dim": 64, +"a_dim": 32 +``` + +含义： + +- `n_dim`：节点表示维度 +- `e_dim`：边表示维度 +- `a_dim`：角表示维度 + +这些参数改变后，descriptor 内部权重矩阵形状会改变。 + +### 2.4 DPA3 层数 + +```json +"nlayers": 24 +``` + +注意：当前工具原始 `input.json` 模板中可能是： + +```json +"nlayers": 16 +``` + +但使用 `DPA-3.2-5M.pt` 并开启 `use_pretrain_script=True` 后，DeePMD-kit 会在 `input_v2_compat.json` / `out.json` 中把它改成预训练模型实际使用的层数，例如： + +```json +"nlayers": 24 +``` + +这类结构参数应以预训练模型为准。 + +### 2.5 cutoff 和 neighbor selection 参数 + +这些参数建议和预训练模型一致： + +```json +"e_rcut": 6.0, +"e_rcut_smth": 5.3, +"e_sel": 1200, +"a_rcut": 4.0, +"a_rcut_smth": 3.5, +"a_sel": 300, +"axis_neuron": 4 +``` + +含义： + +- `e_rcut` / `e_rcut_smth`：边距离 cutoff 与平滑区间 +- `e_sel`：边邻居选择数量 +- `a_rcut` / `a_rcut_smth`：角相关 cutoff 与平滑区间 +- `a_sel`：角邻居选择数量 +- `axis_neuron`：descriptor 内部投影维度相关参数 + +### 2.6 activation 和其他 descriptor 开关 + +预训练兼容后的配置中可能包含： + +```json +"activation_function": "custom_silu:3.0", +"precision": "float32", +"use_tebd_bias": false, +"concat_output_tebd": false, +"use_loc_mapping": true, +"skip_stat": true, +"edge_init_use_dist": true, +"use_exp_switch": true, +"n_multi_edge_message": 1, +"optim_update": true +``` + +这些参数有些会影响模型结构，有些会影响模型计算逻辑。做预训练微调时，不建议手动随意修改。 + +--- + +## 3. 可以根据当前任务设置的参数 + +这些参数主要控制当前微调任务，不需要和预训练模型完全一致。 + +### 3.1 训练数据路径 + +例如： + +```json +"training_data": { + "systems": [ + "prepared_data/train/10", + "prepared_data/train/15" + ] +} +``` + +这些应使用当前任务生成的数据路径。 + +### 3.2 验证数据路径 + +例如： + +```json +"validation_data": { + "systems": [ + "prepared_data/valid/22" + ] +} +``` + +同样由当前任务数据决定。 + +### 3.3 训练步数 + +可以自行设置： + +```python +numb_steps=10 +``` + +或正式训练时设置更大： + +```python +numb_steps=10000 +numb_steps=50000 +numb_steps=200000 +``` + +当前 20 条 demo 数据只用于 smoke test，`10` steps 只是验证流程。 + +### 3.4 batch size + +可以根据数据量和显存调整： + +```python +batch_size=1 +``` + +或使用 DeePMD 支持的自动 batch： + +```python +batch_size="auto:512" +``` + +当前 20 条 demo 数据中很多 system 只有 1-2 个样本，如果设置： + +```python +batch_size=1024 +``` + +会出现 warning： + +```text +required batch size is larger than the size of the dataset +``` + +这不是致命错误，但小数据测试时 `batch_size=1` 更自然。 + +### 3.5 learning rate + +微调通常使用比从头训练更小的学习率。 + +从头训练常见： + +```json +"start_lr": 1e-3 +``` + +预训练微调可用： + +```json +"start_lr": 1e-4, +"stop_lr": 1e-6 +``` + +在 `train_property_20.py` 中可通过 `input_updates` 设置： + +```python +input_updates={ + "learning_rate": { + "type": "exp", + "decay_steps": 1000, + "start_lr": 1e-4, + "stop_lr": 1e-6, + } +} +``` + +### 3.6 loss + +性质预测任务使用： + +```json +"loss": { + "type": "property", + "metric": ["mae", "rmse"], + "loss_func": "smooth_mae", + "beta": 1.0 +} +``` + +这个由新任务决定，不需要和预训练模型原任务一致。 + +### 3.7 property name / property column + +例如： + +```python +property_name="Property" +property_col="Property" +``` + +含义： + +- `property_col`：CSV 中读取哪一列作为标签 +- `property_name`：写入 DeePMD 数据和 fitting net 的性质名 + +如果以后换性质，只需要对应修改这两个参数。 + +### 3.8 property fitting net + +例如： + +```json +"fitting_net": { + "type": "property", + "property_name": "Property", + "intensive": true, + "task_dim": 1, + "neuron": [240, 240, 240] +} +``` + +对于新性质任务，fitting net 通常会重新初始化并训练。日志中出现： + +```text +The fitting net will be re-init instead of using that in the pretrained model! +``` + +表示当前任务使用了新的 property head。 + +初期建议保持默认结构，确认流程稳定后再调 `neuron`、`task_dim` 等参数。 + +### 3.9 freeze + +这是 `deepmd_property_tools` 的工具层参数： + +```python +freeze=False +``` + +它控制训练结束后是否自动导出 `frozen_model.pth`。 + +当前 DPA3 预训练模型的 `custom_silu` 在 TorchScript freeze 阶段可能报错，因此当前 demo 中使用： + +```python +freeze=False +``` + +先保存 checkpoint： + +```text +model.ckpt-10.pt +``` + +并直接用 checkpoint 做预测。 + +### 3.10 `nproc_per_node` + +这是 `deepmd_property_tools` 的训练启动参数，用于控制单节点启动多少个训练进程： + +```python +nproc_per_node=1 +``` + +默认值是 `1`，表示单进程训练。单进程时，工具会直接调用 DeePMD-kit 的 Python 训练入口。 + +如果设置为大于 1，例如： + +```python +nproc_per_node=2 +``` + +工具会改用 `torchrun` 启动多进程训练，等价于： + +```bash +torchrun --nproc_per_node=2 --no-python dp --pt train input.json +``` + +通常含义是单节点 2 张 GPU / 2 个训练进程。8 卡训练可以设置： + +```python +nproc_per_node=8 +``` + +注意：`nproc_per_node` 不是 CPU 线程数。如果只是在 CPU 上想使用更多线程，应通过环境变量控制，例如： + +```bash +export OMP_NUM_THREADS=4 +export DP_INTRA_OP_PARALLELISM_THREADS=4 +export DP_INTER_OP_PARALLELISM_THREADS=2 +python train_property_20.py +``` + +--- + +## 4. 当前推荐配置示例 + +```python +trainer = PropertyTrain( + task="regression", + data_type="molecule", + property_name="Property", + property_col="Property", + save_path=ROOT / "exp_property_20", + numb_steps=10, + batch_size=1024, + model_name="dpa3", + model_size="5m", + freeze=False, + nproc_per_node=1, + finetune=ROOT / "DPA-3.2-5M.pt", + use_pretrain_script=True, + input_updates={ + "learning_rate": { + "type": "exp", + "decay_steps": 1000, + "start_lr": 1e-4, + "stop_lr": 1e-6, + } + }, +) +``` + +对于更正式的训练，可以优先调整： + +```text +numb_steps +batch_size +learning_rate +train_ratio +nproc_per_node +property_name / property_col +``` + +不建议优先手动修改： + +```text +model.descriptor.repflow.* +activation_function +precision +DPA3 结构开关 +``` + +这些应由 `use_pretrain_script=True` 自动继承预训练模型配置。 + +--- + +## 5. 简要总结 + +应继承预训练模型的主要是： + +```text +DPA3 descriptor 结构参数 +repflow 维度、层数、cutoff、sel +activation_function +precision +与 type_map 兼容的元素设置 +``` + +可以自行设置的是： + +```text +训练/验证数据 +batch_size +numb_steps +learning_rate +loss +property_name / property_col +property fitting head +是否 freeze +nproc_per_node +``` + +当前工具推荐让 DeePMD-kit 通过： + +```python +use_pretrain_script=True +``` + +自动继承预训练模型结构，而用户主要调当前任务相关的训练超参。 diff --git a/deepmd/deepmd_property_tools/MANIFEST.in b/deepmd/deepmd_property_tools/MANIFEST.in new file mode 100644

1. 总体原则 - -预训练微调可以理解为： - -```text -DPA3 descriptor 使用预训练模型权重 -property fitting net / property head 面向新性质重新训练 -``` - -因此参数可以分成两类： - -```text -模型结构参数：应尽量和预训练模型一致，否则权重加载会失败 -训练任务参数：可以按当前数据和任务重新设置 -``` - -在当前 `deepmd_property_tools` 中，推荐使用： - -```python -PropertyTrain( - ..., - finetune=PRETRAINED_MODEL, - use_pretrain_script=True, -) -``` - -其中 `use_pretrain_script=True` 会让 DeePMD-kit 根据预训练模型里的 `model_params` 自动修正当前 `input.json` 中的模型结构，使其更容易和 `DPA-3.2-5M.pt` 对齐。 - -______________________________________________________________________ - -## 2. 应与预训练模型保持一致的参数 - -这些参数通常决定模型权重张量的形状或模型 forward 逻辑。如果和预训练模型不一致，容易出现： - -```text -size mismatch -missing key -unexpected key -``` - -### 2.1 `model.type_map` - -示例： - -```json -"type_map": ["H", "C", "N", "O"] -``` - -微调数据中的元素类型应被预训练模型支持。当前 20 条 demo 数据自动生成： - -```json -[ - "H", - "C", - "N", - "O" -] -``` - -如果使用全量数据且包含 `I`，则可能生成： - -```json -[ - "H", - "C", - "N", - "O", - "I" -] -``` - -需要确认预训练模型支持这些元素。 - -### 2.2 `model.descriptor.type` - -必须是： - -```json -"type": "dpa3" -``` - -因为微调目标是继承 DPA3 descriptor。 - -### 2.3 DPA3 repflow 维度参数 - -这些参数应与预训练模型一致： - -```json -"n_dim": 128, -"e_dim": 64, -"a_dim": 32 -``` - -含义： - -- `n_dim`：节点表示维度 -- `e_dim`：边表示维度 -- `a_dim`：角表示维度 - -这些参数改变后，descriptor 内部权重矩阵形状会改变。 - -### 2.4 DPA3 层数 - -```json -"nlayers": 24 -``` - -注意：当前工具原始 `input.json` 模板中可能是： - -```json -"nlayers": 16 -``` - -但使用 `DPA-3.2-5M.pt` 并开启 `use_pretrain_script=True` 后，DeePMD-kit 会在 `input_v2_compat.json` / `out.json` 中把它改成预训练模型实际使用的层数，例如： - -```json -"nlayers": 24 -``` - -这类结构参数应以预训练模型为准。 - -### 2.5 cutoff 和 neighbor selection 参数 - -这些参数建议和预训练模型一致： - -```json -"e_rcut": 6.0, -"e_rcut_smth": 5.3, -"e_sel": 1200, -"a_rcut": 4.0, -"a_rcut_smth": 3.5, -"a_sel": 300, -"axis_neuron": 4 -``` - -含义： - -- `e_rcut` / `e_rcut_smth`：边距离 cutoff 与平滑区间 -- `e_sel`：边邻居选择数量 -- `a_rcut` / `a_rcut_smth`：角相关 cutoff 与平滑区间 -- `a_sel`：角邻居选择数量 -- `axis_neuron`：descriptor 内部投影维度相关参数 - -### 2.6 activation 和其他 descriptor 开关 - -预训练兼容后的配置中可能包含： - -```json -"activation_function": "custom_silu:3.0", -"precision": "float32", -"use_tebd_bias": false, -"concat_output_tebd": false, -"use_loc_mapping": true, -"skip_stat": true, -"edge_init_use_dist": true, -"use_exp_switch": true, -"n_multi_edge_message": 1, -"optim_update": true -``` - -这些参数有些会影响模型结构，有些会影响模型计算逻辑。做预训练微调时，不建议手动随意修改。 - -______________________________________________________________________ - -## 3. 可以根据当前任务设置的参数 - -这些参数主要控制当前微调任务，不需要和预训练模型完全一致。 - -### 3.1 训练数据路径 - -例如： - -```json -"training_data": { - "systems": [ - "prepared_data/train/10", - "prepared_data/train/15" - ] -} -``` - -这些应使用当前任务生成的数据路径。 - -### 3.2 验证数据路径 - -例如： - -```json -"validation_data": { - "systems": [ - "prepared_data/valid/22" - ] -} -``` - -同样由当前任务数据决定。 - -### 3.3 训练步数 - -可以自行设置： - -```python -numb_steps = 10 -``` - -或正式训练时设置更大： - -```python -numb_steps = 10000 -numb_steps = 50000 -numb_steps = 200000 -``` - -当前 20 条 demo 数据只用于 smoke test，`10` steps 只是验证流程。 - -### 3.4 batch size - -可以根据数据量和显存调整： - -```python -batch_size = 1 -``` - -或使用 DeePMD 支持的自动 batch： - -```python -batch_size = "auto:512" -``` - -当前 20 条 demo 数据中很多 system 只有 1-2 个样本，如果设置： - -```python -batch_size = 1024 -``` - -会出现 warning： - -```text -required batch size is larger than the size of the dataset -``` - -这不是致命错误，但小数据测试时 `batch_size=1` 更自然。 - -### 3.5 learning rate - -微调通常使用比从头训练更小的学习率。 - -从头训练常见： - -```json -"start_lr": 1e-3 -``` - -预训练微调可用： - -```json -"start_lr": 1e-4, -"stop_lr": 1e-6 -``` - -在 `train_property_20.py` 中可通过 `input_updates` 设置： - -```python -input_updates = { - "learning_rate": { - "type": "exp", - "decay_steps": 1000, - "start_lr": 1e-4, - "stop_lr": 1e-6, - } -} -``` - -### 3.6 loss - -性质预测任务使用： - -```json -"loss": { - "type": "property", - "metric": ["mae", "rmse"], - "loss_func": "smooth_mae", - "beta": 1.0 -} -``` - -这个由新任务决定，不需要和预训练模型原任务一致。 - -### 3.7 property name / property column - -例如： - -```python -property_name = "Property" -property_col = "Property" -``` - -含义： - -- `property_col`：CSV 中读取哪一列作为标签 -- `property_name`：写入 DeePMD 数据和 fitting net 的性质名 - -如果以后换性质，只需要对应修改这两个参数。 - -### 3.8 property fitting net - -例如： - -```json -"fitting_net": { - "type": "property", - "property_name": "Property", - "intensive": true, - "task_dim": 1, - "neuron": [240, 240, 240] -} -``` - -对于新性质任务，fitting net 通常会重新初始化并训练。日志中出现： - -```text -The fitting net will be re-init instead of using that in the pretrained model! -``` - -表示当前任务使用了新的 property head。 - -初期建议保持默认结构，确认流程稳定后再调 `neuron`、`task_dim` 等参数。 - -### 3.9 freeze - -这是 `deepmd_property_tools` 的工具层参数： - -```python -freeze = False -``` - -它控制训练结束后是否自动导出 `frozen_model.pth`。 - -当前 DPA3 预训练模型的 `custom_silu` 在 TorchScript freeze 阶段可能报错，因此当前 demo 中使用： - -```python -freeze = False -``` - -先保存 checkpoint： - -```text -model.ckpt-10.pt -``` - -并直接用 checkpoint 做预测。 - -### 3.10 `nproc_per_node` - -这是 `deepmd_property_tools` 的训练启动参数，用于控制单节点启动多少个训练进程： - -```python -nproc_per_node = 1 -``` - -默认值是 `1`，表示单进程训练。单进程时，工具会直接调用 DeePMD-kit 的 Python 训练入口。 - -如果设置为大于 1，例如： - -```python -nproc_per_node = 2 -``` - -工具会改用 `torchrun` 启动多进程训练，等价于： - -```bash -torchrun --nproc_per_node=2 --no-python dp --pt train input.json -``` - -通常含义是单节点 2 张 GPU / 2 个训练进程。8 卡训练可以设置： - -```python -nproc_per_node = 8 -``` - -注意：`nproc_per_node` 不是 CPU 线程数。如果只是在 CPU 上想使用更多线程，应通过环境变量控制，例如： - -```bash -export OMP_NUM_THREADS=4 -export DP_INTRA_OP_PARALLELISM_THREADS=4 -export DP_INTER_OP_PARALLELISM_THREADS=2 -python train_property_20.py -``` - -______________________________________________________________________ - -## 4. 当前推荐配置示例 - -```python -trainer = PropertyTrain( - task="regression", - data_type="molecule", - property_name="Property", - property_col="Property", - save_path=ROOT / "exp_property_20", - numb_steps=10, - batch_size=1024, - model_name="dpa3", - model_size="5m", - freeze=False, - nproc_per_node=1, - finetune=ROOT / "DPA-3.2-5M.pt", - use_pretrain_script=True, - input_updates={ - "learning_rate": { - "type": "exp", - "decay_steps": 1000, - "start_lr": 1e-4, - "stop_lr": 1e-6, - } - }, -) -``` - -对于更正式的训练，可以优先调整： - -```text -numb_steps -batch_size -learning_rate -train_ratio -nproc_per_node -property_name / property_col -``` - -不建议优先手动修改： - -```text -model.descriptor.repflow.* -activation_function -precision -DPA3 结构开关 -``` - -这些应由 `use_pretrain_script=True` 自动继承预训练模型配置。 - -______________________________________________________________________ - -## 5. 简要总结 - -应继承预训练模型的主要是： - -```text -DPA3 descriptor 结构参数 -repflow 维度、层数、cutoff、sel -activation_function -precision -与 type_map 兼容的元素设置 -``` - -可以自行设置的是： - -```text -训练/验证数据 -batch_size -numb_steps -learning_rate -loss -property_name / property_col -property fitting head -是否 freeze -nproc_per_node -``` - -当前工具推荐让 DeePMD-kit 通过： - -```python -use_pretrain_script = True -``` - -自动继承预训练模型结构，而用户主要调当前任务相关的训练超参。 diff --git a/deepmd/deepmd_property_tools/MANIFEST.in b/deepmd/deepmd_property_tools/MANIFEST.in deleted file mode 100644 index f78b0137fb..0000000000 ---

That package __init__ eagerly imported tabulate_ops, which registers fake tensor impls for the compressed tabulate custom ops at import time. On the plain pt (torch.jit) backend without the C++ op library, the pt descriptor fallbacks monkeypatch a plain Python function onto torch.ops.deepmd., so the bare hasattr guard passes but register_fake raises "operator deepmd::tabulate_fusion_se_a does not exist", crashing `dp test`. Fix: - Drop the eager tabulate_ops import from pt_expt/utils/__init__.py. The only consumer that needs the fakes (the compression entry point) already calls ensure_fake_registered() lazily, so plain pt inference no longer triggers any custom-op registration. - Harden ensure_fake_registered(): guard each op with a real OpOverloadPacket check (_op_exists) instead of bare hasattr, so a monkeypatched plain-function fallback is skipped rather than crashing.
