Notfittederror python
WebThis is done for efficiency reasons if individual jobs take very little time, but may raise errors if the dataset is large and not enough memory is available. A workaround in this case is to set pre_dispatch. Then, the memory is copied only pre_dispatch many times. A reasonable value for pre_dispatch is 2 * n_jobs. Examples >>> Web使用python对一组数据进行四参数和五参数拟合 首先，你需要准备你的数据，这通常是一个包含两列的数据帧，其中一列是自变量，另一列是因变量。 然后，你需要安装一个名为`scipy`的库，这是一个用于科学计算的 Python 库。

You can then use it to classify your testing data, using the cluster centers computed during the training phase: y_pred = knn.predict(X_test).
