install error from pip

Hi when I type pip install fastdfe

the error occurs

ERROR: Could not find a version that satisfies the requirement fastdfe ERROR: No matching distribution found for fastdfe

Hi! Which python version are you using? Due do fastdfe's dependencies only Python 3.10 and 3.11 are supported. Could it be that you are using a different version? I would recommend using a separate conda environment as described in the docs.

Hi ,my python version iis 3.12.2. I also follow your instruction for install fstDFE by creating a separate conda environment as "environment.yml "

cat environment.yml name: fastdfe channels:

• defaults dependencies:
• python
• pip
• pip:
  • fastdfe conda env create -f environment.yml Pip subprocess error: ERROR: Ignored the following versions that require a different python version: 0.1.1b0 Requires-Python >=3.10,<3.12; 0.1.2b0 Requires-Python >=3.10,<3.12; 0.1.3b0 Requires-Python >=3.10,<3.12; 0.1.4b0 Requires-Python >=3.10,<3.12; 0.1.5b0 Requires-Python >=3.10,<3.12; 0.1.6b0 Requires-Python >=3.10,<3.12; 0.1.7b0 Requires-Python >=3.10,<3.12; 0.1.8b0 Requires-Python >=3.10,<3.12; 1.0.0 Requires-Python >=3.10,<3.12; 1.1.0 Requires-Python >=3.10.0,<3.12; 1.1.1 Requires-Python >=3.10.0,<3.12; 1.1.2 Requires-Python >=3.10.0,<3.12; 1.1.3 Requires-Python >=3.10.0,<3.12; 1.1.4 Requires-Python >=3.10.0,<3.12 ERROR: Could not find a version that satisfies the requirement fastdfe (from versions: none) ERROR: No matching distribution found for fastdfe

failed

CondaEnvException: Pip failed python --version Python 3.12.2

I suppose it is still installing python 3.12 as the pip dependencies are only added later in a separate step. If you restrict the python versions to 3.10 and 3.11, it should work. I will update this in the docs:

name: fastdfe
channels:
  - defaults
dependencies:
  - python>=3.10,<3.12
  - pip
  - pip:
      - fastdfe

Many thanks for your quickly reply, it's working perfect for this command !!

Best, Lin
