这个错误提示说明你在一个NumPy数组上调用了Pandas DataFrame的方法,而NumPy数组并没有`drop_duplicates()`方法,因此出现了`AttributeError`错误。 如果要在NumPy数组上过滤重复行,可以使用`np.unique()`函数。你可以将`y_pred`数组传给该函数,将`axis`参数设置为0来指定按行过滤重复值,将`return_index`参数设置为True来返回保留的第一个索引,将`return_inverse`参数设置为True来返回保留的索引数组。例如: ```python import numpy as np # 假设这是你的预测结果 y_pred = np.array([[1, 2, 3], [4, 5, 6], [1, 2, 3], [7, 8, 9], [4, 5, 6]]) # 使用np.unique()函数过滤重复行 unique_y_pred, indices = np.unique(y_pred, axis=0, return_index=True, return_inverse=True) # 打印结果 print("过滤重复行后的数组:\n", unique_y_pred) ``` 这段代码将返回过滤重复行后的数组`unique_y_pred`和保留的第一个索引数组`indices`,你可以根据需要进行进一步处理。

Traceback (most recent call last): File "D:\anaconda\lib\site-packages\IPython\core\interactiveshell.py", line 3460, in run_code exec(code_obj, self.user_global_ns, self.user_ns) File "<ipython-input-3-de046003dae8>", line 4, in <module> model = torch.load('D://大乐透5.h5') File "D:\anaconda\lib\site-packages\torch\serialization.py", line 713, in load return _legacy_load(opened_file, map_location, pickle_module, **pickle_load_args) File "D:\anaconda\lib\site-packages\torch\serialization.py", line 920, in _legacy_load magic_number = pickle_module.load(f, **pickle_load_args) _pickle.UnpicklingError: invalid load key, 'H'.

这个错误发生的原因是你正在尝试使用 PyTorch 中的 `torch.load()` 函数来加载一个 Keras 模型文件。Keras 模型文件通常是以 ".h5" 为扩展名,而 PyTorch 使用的默认扩展名是 ".pth" 或 ".pt"。 如果你要加载 Keras 模型文件,应该使用 Keras 中提供的函数,例如 `keras.models.load_model()`。示例代码如下: ```python import keras # 加载 Keras 模型 model = keras.models.load_model('D://大乐透5.h5') # 查看模型结构 print(model.summary()) # 修改模型结构 model.layers.pop() # 删除最后一层 model.add(keras.layers.Dense(10, activation='softmax')) # 添加一个新的输出层 # 保存修改后的模型 model.save('modified_model.h5') ``` 这里的代码假设你已经有一个名为 `D://大乐透5.h5` 的 Keras 模型文件。你可以使用 `model.summary()` 函数查看模型结构。这里的代码将删除模型的最后一层,并添加一个新的输出层,最后将修改后的模型保存为 `modified_model.h5`。

根据你提供的信息,看起来你在导入一个名为 custom 的 Python 包时遇到了问题。更具体地说,该包的初始化模块(__init__.py)尝试导入 custom 模块,但是 custom 模块中的某些代码需要 RNA 模块,但是该模块无法找到。 解决此问题的最佳方法是确保 RNA 模块已正确安装。你可以尝试在终端或命令提示符下运行以下命令:pip install RNA 如果你已安装 RNA 模块但仍然遇到此错误,请确保该模块已在 Python 路径中可用。你可以尝试在 Python 中运行以下代码来检查模块是否可用: ```python import RNA ``` 如果此代码运行时未引发 ImportError,则说明模块已正确安装并且在 Python 路径中可用。如果它引发 ImportError,则可能需要将模块的路径添加到 Python 路径中,或者重新安装模块以确保它正确安装。
