Python setting up errors

I am using Azure DSVM Standard DS12 v2 (4 vcpus, 28 GB memory) with Linux, which pre-installed Anaconda and related machine learning tools. It is sometimes confusing as Python 2 and 3 are being used through Jupyter notebook in one machine, and I would like to keep memos when setting up errors happen.


1. Install pydotplus

Command

``` pip install pydotplus ```

Error message

``` Traceback (most recent call last): File "/usr/bin/pip", line 9, in <module> from pip import main ImportError: cannot import name main ```

It looks like "a pip version" installed through "apt" does not match "another pip version" upgraded through "pip install --upgrade pip". I heard it is better to use only "apt" for installing and upgrading "pip". I uninstalled pip once and then installed through "apt" again with commands below, and the issue was solved in my case.

``` python -m pip uninstall pip sudo apt install python-pip pip install pydotplus ```

2. Install Keras

After downloading Keras from github, I faced this error message.

Command

``` (venv) ~/tensorflow$ git clone https://github.com/keras-team/keras.git (venv) ~/tensorflow$ cd keras (venv) ~/tensorflow/keras$ sudo python setup.py install ```

Error message

``` Traceback (most recent call last): File "setup.py", line 1, in <module> from setuptools import setup ImportError: No module named setuptoo ```

It seems this error happens when setuptool is not installed system wide for Ubuntu. The problem was solved with the commands below.

``` sudo apt-get install -y python-setuptools sudo python setup.py install ```
