Python XGBoost GPU 错误：检查失败：gpu_predictor

问题描述

我正在运行以下代码

import xgboost as xgb
from sklearn.datasets import fetch_covtype
from sklearn.model_selection import train_test_split
import time

# Fetch dataset using sklearn
cov = fetch_covtype()
X = cov.data
y = cov.target

# Create 0.75/0.25 train/test split
X_train,X_test,y_train,y_test = train_test_split(X,y,test_size=0.25,train_size=0.75,random_state=42)

# Specify sufficient boosting iterations to reach a minimum
num_round = 3000

# Leave most parameters as default
param = {'objective': 'multi:softmax',# Specify multiclass classification
         'num_class': 8,# Number of possible output classes
         'tree_method': 'gpu_hist' # Use GPU accelerated algorithm
         }

# Convert input data from numpy to XGBoost format
dtrain = xgb.DMatrix(X_train,label=y_train)
dtest = xgb.DMatrix(X_test,label=y_test)

gpu_res = {} # Store accuracy result
tmp = time.time()
# Train model
xgb.train(param,dtrain,num_round,evals=[(dtest,'test')],evals_result=gpu_res)
print("GPU Training Time: %s seconds" % (str(time.time() - tmp)))

# Repeat for cpu algorithm
tmp = time.time()
param['tree_method'] = 'hist'
cpu_res = {}
xgb.train(param,evals_result=cpu_res)
print("cpu Training Time: %s seconds" % (str(time.time() - tmp)))

我收到以下错误：

我怀疑是我当前的python版本不兼容造成的：3.8.3

（默认，2020 年 7 月 2 日，16:21:59）[GCC 7.3.0]
