解决Tensorflow2.0 tf.keras.Model.load_weights() 报错处理问题
这个错误是因为你在调用某个函数时传入了多个评估指标,而该函数不支持同时对多个指标进行评估。建议使用 sklearn.model_selection.cross_validate 函数来对多个指标进行评估。你可以将评估指标作为参数传递给该函数。例如:
```python
from sklearn.model_selection import cross_validate
from sklearn.linear_model import LogisticRegression
from sklearn.datasets import make_classification
X, y = make_classification(random_state=0)
clf = LogisticRegression(random_state=0)
scoring = ['accuracy', 'precision_macro', 'recall_macro']
scores = cross_validate(clf, X, y, scoring=scoring)
```
这样就可以同时对 accuracy、precision_macro 和 recall_macro 三个指标进行评估了。
