[英]ERROR conda.core.link:_execute(502): An error occurred while installing package 'conda-forge::astor-0.7.1-py_0'
I am trying to follow a Python tutorial and I have been able to execute almost everything, until the point of Deploying an endpoint to Azure with python.我正在尝试遵循 Python 教程,并且我已经能够执行几乎所有内容,直到使用 python 将端点部署到 Azure 为止。
In order to give some context I have uploaded the scripts to my git account: https://github.com/levalencia/MLTutorial为了提供一些上下文,我已将脚本上传到我的 git 帐户: https : //github.com/levalencia/MLTutorial
File 1 and 2 Work perfectly fine文件 1 和 2 工作得很好
However the following section in File 3 fails:但是文件 3 中的以下部分失败:

models=[amlModel],
inference_config=inference_config,
deployment_config=aciconfig)
service.wait_for_deployment(show_output=True)
with below error:有以下错误:

==> WARNING: A newer version of conda exists. <==
current version: 4.5.11
latest version: 4.8.2
Please update conda by running
$ conda update -n base -c defaults conda
Unfortunately there seems to an issue with this version of Conda (4.5.11).不幸的是,此版本的 Conda (4.5.11) 似乎存在问题。 To complete this task in the tutorial, you can just update the dependency for Tensorflow and Keras to be from
pip
and not conda
.要在本教程中完成此任务,您只需将 Tensorflow 和 Keras 的依赖项更新为来自
pip
而不是conda
。 There are reasons why this is less than ideal for a production environment.这对于生产环境来说不太理想是有原因的。 The Azure ML documentation states :
Azure ML 文档指出:
"If your dependency is available through both Conda and pip (from PyPi), use the Conda version, as Conda packages typically come with pre-built binaries that make installation more reliable."
“如果您的依赖项可通过 Conda 和 pip(来自 PyPi)获得,请使用 Conda 版本,因为 Conda 软件包通常带有使安装更可靠的预构建二进制文件。”
In this case though, if you update the following code block:在这种情况下,如果您更新以下代码块:
from azureml.core.conda_dependencies import CondaDependencies
myenv = CondaDependencies()
myenv.add_conda_package("tensorflow")
myenv.add_conda_package("keras")
with open("myenv.yml","w") as f:
f.write(myenv.serialize_to_string())
# Review environment file
with open("myenv.yml","r") as f:
print(f.read())
To be the following:如下:
from azureml.core.conda_dependencies import CondaDependencies
myenv = CondaDependencies()
myenv.add_pip_package("tensorflow==2.0.0")
myenv.add_pip_package("azureml-defaults")
myenv.add_pip_package("keras")
with open("myenv.yml", "w") as f:
f.write(myenv.serialize_to_string())
with open("myenv.yml", "r") as f:
print(f.read())
The tutorial should be able to be completed.教程应该可以完成。 Let me know if any of this does not work for you once this update has been made.
完成此更新后,如果其中任何一项对您不起作用,请告诉我。
I have also reported this issue to Microsoft (in regards to the Conda version).我也向微软报告了这个问题(关于 Conda 版本)。
