这段代码中,`poscar_to_feature_vector` 函数定义在 `for` 循环内部,导致无法在循环外部使用该函数。你需要将 `poscar_to_feature_vector` 函数定义移动到循环外部。另外,你需要将 `feature_vector` 添加到 `features` 列表中的操作放在 `poscar_to_feature_vector` 函数内部,否则 `features` 列表将会只包含最后一个 `feature_vector`。修改后的代码如下:
```
features = []
# 定义 poscar_to_feature_vector 函数
def poscar_to_feature_vector(poscar_file):
# 读取原子坐标和原子数目
atoms = read(poscar_file)
coords = atoms.positions
num_atoms = len(atoms)
# 定义特征向量长度
feature_length = num_atoms * 3
feature_vector = np.zeros(feature_length)
# 将每个原子的坐标添加到特征向量中
for i in range(num_atoms):
feature_vector[i*3] = coords[i][0]
feature_vector[i*3+1] = coords[i][1]
feature_vector[i*3+2] = coords[i][2]
# 将 feature_vector 添加到 features 列表中
features.append(feature_vector)
# 遍历 poscars 列表,将每个 POSCAR 文件转换为特征向量并添加到 features 列表中
for poscar in poscars:
poscar_to_feature_vector(poscar)
```
希望这能帮到你!
