unable to create the conda environment with linux-cpu-env.yml

[Superyoutiao]

coconda env create -f environment/linux-cpu-env.yml
Collecting package metadata (repodata.json): done
Solving environment: failed

ResolvePackageNotFound:

• python-dateutil==2.6.1=py35_0
• joblib=0.9.4
• numba==0.35.0=np111py35_0
• matplotlib==2.0.2=np111py35_0
• path.py==10.3.1=py35_0
• python=3.5.2
• mako==1.0.6=py35_0

It's my first time to see this problem. Is the .yml file out-of-date or should I modify it?

it seems that some old version of packages can't be found if the free channel is not used. This can be solved by execute conda config --set restore_free_channel true before install the conda env. Then I met this problem:

Pip subprocess error:
parso requires Python '>=3.6' but the running Python is 3.5.2
You are using pip version 10.0.1, however version 20.3.4 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

failed

CondaEnvException: Pip failed

If I change python = 3.5.2 into python = 3.6, there will be conflicts, any suggestions?

Try adding - parso==0.7.1 to the pip dependencies, i.e. below -pip: in the linux-cpu-env.yml file.
