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

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.

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.

I have a hard time to to connect Eikon API now, after changing the anyio version to 3.2.1 in the Anaconda folder. I followed the guide and my outputs are listed below. Please advise on my next steps. Thank you.

https://developers.refinitiv.com/en/article-catalog/article/eikon-data-api-python-troubleshooting-refinitiv

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.

anyio misses another attribute called 'abc' now.

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

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.
