Hello, I need help installing lseg python library

julien.lebon-lafond01 · November 2024

You'll find below the error message generated. It seems there is a problem with Numpy dependency. The version of Numpy is 2.1.2 .

Hi @julien.lebon-lafond01 ,

Lseg data will try to install numpy version of 1.25.2. Please try installing that version of numpy manually before running pip install lseg.data.

Best regards,

Hello @julien.lebon-lafond01

I suggest you use the Python version 3.10 (download here) and use the Python virtual environment to avoid the library version conflict as mentioned by my colleague above.

You can create a new Python environment, then install and use the LSEG Data Library in that environment, so the installed libraries will not conflict with your main Python installation.

This is the result from my Python 3.10.15 virtual environment:

You may try to use the following command.

pip install --no-cache-dir lseg-data

I have the same problem. I tried all advices above, but I always get the following error:

I have installed the current version 3.13.1 of Python. I tried to install the numpy-version 1.25.2 before installing lseg-data - but that made no difference.
I am a beginner and currently at a loss!
Can somebody help me?
