AttributeError: module 'anyio' has no attribute 'Lock'

clli

Hi,

I face this error message when running python with eikon api today. The error message is module 'anyio' has no attribute 'Lock'. I have already downgraded the anyio version from 3.4.0 to 3.2.1, but the problem stays. How to solve this problem?

Thanks.

@clli

You can try the following code.

import anyio
anyio.Lock()

Next, check the version of anyio in the C:\users\clli\python_prod\Lib\site-packages directory.

clli

Thanks. Do you have any other recommended solution? I tried but I still face this issue.

@clli

My anyio-3.2.1 has the Lock attribute.

I found that anyio below 3.x (such as 2.2.0) doesn't have the Lock attribute.

You can check to code why the anyio doesn't have the Lock attribute.

import anyio
print(anyio.__file__)
print(open(anyio.__file__).read())

I assumed that you are still loading the old version of anyio.

clli

Thanks. I did not see the Lock attribute in anyio. my anyio version is 3.2.1. I have attached the output here. Please assist with my next step. Thanks.

The file is similar to the __init__.py of anyio-2.2.0.

It uses the anyio from C:\ProgramData\Anaconda3\lib\site-packages directory. Please check the version of anyio in this C:\ProgramData\Anaconda3\lib\site-packages directory

Hello @clli

I am noticed that the libraries are located on both "C:\users\<user>\python_prod\Lib\site-packages\" and "C:\ProgramData\Anaconda3\lib\site-packages\" location.

Could you create a new Conda environment, install the Eikon Data API library in that environment and re-test the issue? You can find more detail on the Isolated development environment section of the Setting up a Python development environment tutorial page.

1. My Eikon Desktop version:4.0.55

2. My Eikon Data APIs version:1.1.14

3.Verify that Eikon Desktop is running properly and APIPROXY service is enabled: There imight be something wrong in the API Proxy file.

Thanks. the no attribute 'Lock' issue is solved by moving the anyio 3.2.1 folder from the prod folder to the C:\ProgramData\Anaconda3\lib\site-package folder, but I faced another message - Check if Eikon Desktop or Eikon API Proxy is running. I have read the troubleshooting guide and show the output in an answer below. Should I downgrade my Eikon version, too? If so, please let me know which version I should downgrade to. Thanks.

First, we need to check if the Eikon API proxy is running properly by accessing the following URLs via a web browser.

• http://127.0.0.1:9000/ping?all
• http://127.0.0.1:9060/api/status

The output looks like this:

Next, you need to set up a new virtual environment in Conda, as mentioned by my colleague. Then, install the Eikon library in that environment to verify what the problem is.
