module 'xgboost.callback' has no attribute 'print_evaluation'

这个错误通常是因为您正在使用的XGBoost版本不支持print_evaluation()函数。这个函数在旧版本中被弃用了。如果您想使用这个函数，您需要使用支持它的旧版本。您可以通过以下命令安装旧版本的XGBoost：

pip install xgboost==0.90

如果您想使用新版本的XGBoost，您可以使用以下代码替代print_evaluation()函数：

def print_evaluation(model, period=1, show_stdv=True):
    results = model.evals_result()
    epochs = len(results['validation_0']['error'])
    x_axis = range(period, epochs)
    fig, ax = plt.subplots()
    ax.plot(x_axis, results['validation_0']['error'][period:], label='Train')
    if show_stdv:
        ax.fill_between(x_axis, 
                        (results['validation_0']['error'] - results['validation_0']['stderr'])[period:], 
                        (results['validation_0']['error'] + results['validation_0']['stderr'])[period:], 
                        alpha=0.1, color='g')
    ax.plot(x_axis, results['validation_1']['error'][period:], label='Test')
    if show_stdv:
        ax.fill_between(x_axis, 
                        (results['validation_1']['error'] - results['validation_1']['stderr'])[period:], 
                        (results['validation_1']['error'] + results['validation_1']['stderr'])[period:], 
                        alpha=0.1, color='r')
    ax.legend()
    plt.ylabel('Error')
    plt.title('XGBoost Error')
    plt.show()
