重新安装 timesFM 记录一下过程

1. 安装环境 conda create --name a310 python=3.10.15

(base) root@VM-5-128-ubuntu:/workspace# conda activate a310

2. 安装 pyenv

curl https://pyenv.run | bash

3. 修改 .bash_profile

文件在 root 下

export PYENV_ROOT="$HOME/.pyenv"
[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
export PATH="/root/.local/bin:$PATH"

4.刷新环境变量，这时后才会生效，执行以下代码

source ~/.bash_profile

5. check

(a310) root@VM-5-128-ubuntu:/workspace# pyenv --version
pyenv 2.5.0

6. 安装 poetry

(a310) root@VM-5-128-ubuntu:/workspace# pip install poetry


(a310) root@VM-5-128-ubuntu:/workspace# poetry --version
Poetry (version 1.8.5)

7. 安装 pyenv install 3.10.15

中间出现多次报错

    raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['/tmp/python-build.20241229151142.3168/Python-3.10.15/python', '-W', 'ignore::DeprecationWarning', '-c', '\nimport runpy\nimport sys\nsys.path = [\'/tmp/tmp8oem7l6p/setuptools-65.5.0-py3-none-any.whl\', \'/tmp/tmp8oem7l6p/pip-23.0.1-py3-none-any.whl\'] + sys.path\nsys.argv[1:] = [\'install\', \'--no-cache-dir\', \'--no-index\', \'--find-links\', \'/tmp/tmp8oem7l6p\', \'--root\', \'/\', \'--upgrade\', \'setuptools\', \'pip\']\nrunpy.run_module("pip", run_name="__main__", alter_sys=True)\n']' returned non-zero exit status 1.
make: *** [Makefile:1280: install] Error 1

 错误分析  zlib 模块缺失

先安装 sudo

apt-get install sudo

手动安装 pip 和 setuptools

wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
pip install setuptools

安装 zlib 库
sudo apt-get update
sudo apt-get install zlib1g-dev

在执行pyenv install 3.10.15

执行 pyenv versions 检查 后 这个命令会列出所有已安装的 Python 版本，你应该能在列表中看到3.10.15。

发现仍未正确安装

执行这两个代码

sudo apt-get update

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
> libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
> xz-utils tk-dev libffi-dev liblzma-dev python-openssl

安装完依赖后，再使用pyenv安装 Python 3.10.15：

pyenv install 3.10.15

 执行 pyenv versions 检查

(base) root@VM-5-128-ubuntu:/workspace/timesfm# pyenv versions
* system (set by /root/.pyenv/version)
  3.10.15

再安装 python 3.11

执行 pyenv versions 

(base) root@VM-5-128-ubuntu:/workspace/timesfm# pyenv versions
* system (set by /root/.pyenv/version)
  3.10.15
  3.11.11

 poetry env use 3.10.15

(base) root@VM-5-128-ubuntu:/workspace/timesfm# poetry env use 3.10.15
Creating virtualenv timesfm-p1AFFT58-py3.10 in /root/.cache/pypoetry/virtualenvs
Using virtualenv: /root/.cache/pypoetry/virtualenvs/timesfm-p1AFFT58-py3.10

poetry lock

poetry install -E  pax

(base) root@VM-5-128-ubuntu:/workspace/timesfm# poetry install -E  pax
Installing dependencies from lock file

After than you can run the timesfm under `poetry shell` or do `poetry run python3 ...`

base) root@VM-5-128-ubuntu:/workspace/timesfm# poetry run python3 -m vehicle_fcst --model_path=google/timesfm-1.0-200m

vehicle_fcst.py 代码如下

import os
import gc
import numpy as np
import pandas as pd
from timesfm import TimesFm, TimesFmHparams, TimesFmCheckp
