Python OSError:[Errno 9]使用GridSearchCV的文件描述符不正确

我很难弄清楚我的代码有什么问题。 我是python世界的新手，请原谅我的语法问题。 感谢所有愿意花时间帮助我的人。 这是我的代码：

X_train=np.random.randn(4000,400)

y_train=np.random.randn(4000)

parameters={
    "solver":("auto", "svd", "cholesky", "lsqr", "sparse_cg", "sag", "saga"),

    "tol":[1e-3,1e-5,1e-8],

    "alpha":[1,1.2,1.4,1.5],

    "random_state":[42]

}

reg= Ridge()

clf = GridSearchCV(reg, parameters,scoring="r2", n_jobs=-1,cv=5)

clf.fit(X_train,y_train) **here's where troubles happen**

print(clf.best_score_)

print(clf.best_params_)

File"/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/_pydevd_bundle/pydevd_comm.py", line 290, in _on_run

r = self.sock.recv(1024)

OSError: [Errno 9] Bad file descriptor

下面是错误：

X_train=np.random.randn(4000,400)

y_train=np.random.randn(4000)

parameters={
    "solver":("auto", "svd", "cholesky", "lsqr", "sparse_cg", "sag", "saga"),

    "tol":[1e-3,1e-5,1e-8],

    "alpha":[1,1.2,1.4,1.5],

    "random_state":[42]

}

reg= Ridge()

clf = GridSearchCV(reg, parameters,scoring="r2", n_jobs=-1,cv=5)

clf.fit(X_train,y_train) **here's where troubles happen**

print(clf.best_score_)

print(clf.best_params_)
