问题描述

我在 azure 环境中创建了一个工作区并尝试运行此代码：

Performing interactive authentication. Please follow the instructions on the terminal.
Note,we have launched a browser for you to login. For old experience with device code,use "az login --use-device-code"
You have logged in. Now let us find all the subscriptions to which you have access...
Interactive authentication successfully completed.

AuthenticationException: AuthenticationException:
        Message: Could not retrieve user token. Please run 'az login'
        InnerException It is required that you pass in a value for the "algorithms" argument when calling decode().
        ErrorResponse
{
    "error": {
        "code": "UserError","inner_error": {
            "code": "Authentication"
        },"message": "Could not retrieve user token. Please run 'az login'"
    }
}

一些交互式身份验证器在我的浏览器中打开，我认为这是预期行为，因为我没有租户。但是，我明白了：

az login

我也试过：

t1 = read.dendrogram("F:/Neighbor-joining-tree.newick")
t1 = dendrapply(t1,function(x) {
 if(is.leaf(x)) {
    attr(x,"height") = 0
  }
 x
})
hist_minor <- Heatmap(minor,column_title = "Statistics for a list of SNP.Frequency.minor",column_title_gp = gpar(fontsize = 15,fontface = "bold"),column_names_gp = gpar(fontsize = 10),row_title = "Genome Postion(bp)",row_title_gp = gpar(fontsize = 10),name = "Variant.Frequency",cluster_rows = FALSE,cluster_columns = t1,use_raster = TRUE,raster_resize_mat = max,right_annotation = ha,show_row_names = FALSE,col = cols,column_dend_height= unit(3,"cm"),#column_dend_height= unit(6,"cm")
                  border_gp = gpar(col = "black",lty = 2)
)

这很好用。所以对我来说，这一切都非常令人困惑！

解决方法

所以我在 Python 中尝试了相同的方法并遇到了类似的错误并遇到了这个：

https://github.com/Azure/azure-sdk-for-python/issues/16035

降级：

 PyJWT

有帮助。奇异的开源世界及其相互依存的网络！

正如@cs0815 提到的，这个 Github 问题帮助我解决了这个问题： https://github.com/Azure/azure-sdk-for-python/issues/16035

我做了什么来解决这个问题？

1.检查软件包版本

运行以下命令时，我使用的是 azure-core 版本 1.15.0：

pip show azure-core

当我运行这个命令时，我的 PyJWT 是 2.1.0：

pip show PyJWT

2.将 PyJWT 降级到 1.7.1

为此，我运行以下命令：

python -m pip install --upgrade PyJWT==1.7.1

3.检查工作区连接

我运行此 Python 脚本以连接到我的 Azure 机器学习工作区：

import azureml.core
from azureml.core import Workspace

print("Ready to use Azure ML",azureml.core.VERSION)

#Store first the workspace connection information in a JSON.
#This can be downloaded from the Azure portal or the workspace details
#pane in Azure Machine Learning studio.
ws = Workspace.from_config('config.json')
print(ws.name,"loaded")
