I'm just trying to learn Tensorflow, but am totally new to Python, so I'm using Anaconda I created a conda environment:
$ conda create −n tensorflow python =3.5
Of course I activated my conda environment
$ source activate tensorflow
Then I played a bit around in Spyder, tried to plot a MNIST-digit (copy-paste code from my tutor which is tested several times), it includes of course
import matplotlib.pyplot as plt
[...]
plt.plot(number)
but executing the Python file with bash gives me:
(tensorflow) leon@leon-linux:~/ANNsCourse/Session1$ python helloWorld.py
Traceback (most recent call last):
File "helloWorld.py", line 10, in <module>
import matplotlib.pyplot as plt
ImportError: No module named 'matplotlib'
I'm quite confused right now, as the (tensorflow) in the bash obviously denotes that my conda tensorflow environment works (at least from my understanding). Also, from what I understood, conda should have matplotlib built in, right? And it should also load this in my conda tensorflow environment, right? This is what my tutor's slide said
There is no need to install further packages like numpy or matplotlib, since Anaconda contains current versions of them already.'
and also what I was able to take from everything I Googled and StackOverflowed. Neither Googling nor StackOverflowing gave me any good answer (might also just be because I don't understand enough yet).
My best guess would be that I still have to include matplotlib into my tensorflow conda environment, but this would be contradicting both my tutor & Google, while I also would not know how to do this.
edit: conda list gave me that matplotlib was not in my tensorflowenvironment, so I went
conda install matplotlib
I'm still afraid something is wrong with my conda tensorflow environment, shouldn't the matplotlib have been in there by default? It also told me:

Which tells me also numpy was missing? Can someone confirm this to be correct now, or is there something fishy with my conda?
You just created a conda environment named tensorflow and switched into it. You haven't installed the tensorflow package or any of the default anaconda packages.
To do that, do
conda create -n tensorflow python=3.5 anaconda # install anaconda3 default packages
source activate tensorflow # switch into it
conda install -c conda-forge tensorflow # install tensorflow
