Note that strict channel priority may have removed packages required for satisfiability.
我不知道如何解释这个输出。以下面的 numba 声称的包冲突列表为例：
Package numba conflicts for:
rapids=0.14 -> cudf=0.14 -> numba[version='>=0.40.1|>=0.49.0|>=0.49']
rapids=0.14 -> numba[version='>=0.49,<0.50a']
这似乎很容易满足：只需安装 numba==0.49。日志中似乎充满了此类无法解决的无法解决的冲突。
有谁知道为什么 conda 提供这样的输出？
只是 运行 :
conda install \
-c conda-forge \
-y \
-q \
dask-yarn>=0.7.0 \
pyarrow \
s3fs \
conda-pack \
tornado=5 \
python=3.7 \
bokeh \
fastparquet \
python-snappy \
snappy \
rapids=0.14 cudatoolkit=10.2
无需更新 conda config 在我的系统中对我有用。所有必需的库都已安装，没有任何问题或错误。为什么要更新 conda config？
即使你让它工作，这将无法安装 RAPIDS，因为 m5 实例没有 GPU。您需要 AWS 的 p3 或 g4 实例。
正在尝试以下 conda install 操作（源自 NVIDIA RAPIDS installation instructions）：
conda config --prepend channels rapidsai && \
conda config --prepend channels nvidia && \
conda config --set channel_priority strict && \
conda install \
-c conda-forge \
-y \
-q \
dask-yarn>=0.7.0 \

在 AWS EC2 实例（具体来说，m5.xlarge）上，此操作失败，以下（滑稽地长；我在这里提供了一个片段，click here for a gist with the full version）输出解释了包冲突：

我不知道如何解释这个输出。以下面的 numba 声称的包冲突列表为例：
Package numba conflicts for:
rapids=0.14 -> cudf=0.14 -> numba[version='>=0.40.1|>=0.49.0|>=0.49']
rapids=0.14 -> numba[version='>=0.49,<0.50a']
这似乎很容易满足：只需安装 numba==0.49。日志中似乎充满了此类无法解决的无法解决的冲突。
有谁知道为什么 conda 提供这样的输出？
只是 运行 :
conda install \

-q \

无需更新 conda config 在我的系统中对我有用。所有必需的库都已安装，没有任何问题或错误。为什么要更新 conda config？
即使你让它工作，这将无法安装 RAPIDS，因为 m5 实例没有 GPU。您需要 AWS 的 p3 或 g4 实例。
