从 numba 导入 cuda、numpy_support 和 ImportError：无法从'numba'导入名称'numpy_support'

Question

我正在将pandas改为cudf，以便更快地聚合并降低处理速度。我找到了一个可以在GPU上使用pandas的库。

"CUDF LINK"https://github.com/rapidsai/cudf

当我在我的项目中输入以下内容安装时，它给出了一个错误，我也尝试了许多版本的numba。

conda install -c rapidsai -c nvidia -c numba -c conda-forge 
cudf=0.13 python=3.7 cudatoolkit=10.2

当尝试安装cuDF 0.13时，conda显然找到了与cuDF 0.13不兼容的numba版本。

cuDF 0.13已过期。当前的稳定版本是0.17，夜间版本是0.18。我们将更新README，因为它应该提供当前版本的安装说明。

我们建议创建一个新的conda环境。请尝试下面的conda安装命令，在这里找到:

conda create -n rapids-0.17 -c rapidsai -c nvidia -c conda-forge 
-c defaults rapids-blazing=0.17 python=3.7 cudatoolkit=10.2
