定制环境jupyter笔记本

Question

我希望为我的Jupyter笔记本电脑创建自定义环境，而不必在会话中安装各种软件包。

按照https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/customize-envs.html的说明，我按如下方式定制了环境>

# Modify the following content to add a software customization to an environment.
# To remove an existing customization, delete the entire content and click Apply.

# Add conda channels below defaults, indented by two spaces and a hyphen.
channels:
  - defaults

# To add packages through conda or pip, remove the comment on the following line.
# dependencies:

# Add conda packages here, indented by two spaces and a hyphen.
# Remove the comment on the following line and replace sample package name with your package name:
  - ffmpeg=4.2.2

# Add pip packages here, indented by four spaces and a hyphen.
# Remove the comments on the following lines  and replace sample package name with your package name.
  - pip:
    - numpy==1.18.0
    - pandas==1.0.3
    - matplotlib==3.1.3
因为我的笔记本和最新版本的pandas，numpy和matplotlib需要mpeg编解码器。 

配置是

Environment             Custom env
Creator                 Andrea Chiappo
Language                Python 3.6
Hardware configuration  4 vCPU and 16 GB RAM
Software configuration  Default Python 3.6 + DO
但是，一旦我开始会话，如果尝试的话

import pandas as pd
print(pd.__version__)
我得到了程序包的默认版本，即0.24.1。 

有人知道如何在我的jypter会话中启用此类Python软件包的最新版本吗？非常感谢

您需要取消注释# dependencies:行。并且随时摆脱所有评论。这将有助于发现YAML格式的缩进问题。试试这个：
