我正在尝试实现贝叶斯优化,但在从 skopt 导入 gp_minimize 的 scikit-optimize 包中导入“gp_minimize”时已经开始出错

`

res = gp_minimize(f,                  # the function to minimize
                  [(-2.0, 2.0)],      # the bounds on each dimension of x
                  acq_func="EI",      # the acquisition function
                  n_calls=15,         # the number of evaluations of f
                  n_random_starts=5,  # the number of random initialization points
                  noise=0.1**2,       # the noise level (optional)
                  random_state=1234)   # the random seed*

ModuleNotFoundError: No module named 'sklearn.externals.joblib'

` 我已经下载了所有必需的包,例如 joblib 和 scikit learn 和 scikit optimize,所以不知道为什么它不起作用。

解决方案 = 最后,我再次重新安装了 Anaconda et scikit-optimizer,一切正常。
