export Environment_Variable = something --> = [equals sign] not a valid identifier

Question

I'm still quite new to Ubuntu.

I've been installing tensorflow (with CUDA) for some university project; we are to work in conda. After activating my tensorflow conda environment, my instructions tell me to set the path (which is, as far as I understand an environment variable?) for pip installation:

Next, set the path to the binary file for the pip installation, by typing the following command:

( t e n s o rfl o w ) $ export TF BINARY URL = \
h t t p s : / / s t o r a g e . g o o g l e a p i s . com/ t e n s o rf l o w / li n u x /\
cpu/ t e n s o rfl o w −0.11.0 rc1−cp35−cp35m−li n u x x 8 6 6 4 . whl

To finalize the installation type:

( t e n s o rfl o w ) $ pip3 i n s t a l l −−ig no r e−i n s t a l l e d \
−−upgrade $TF BINARY URL

You can now proceed with Test run TensorFlow.

(All the spaces just come from the latex-pdf, of course I left them out.)

So I typed:

export TF_BINARY_URL = https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.11.0rc1-cp35-cp35m-linux_x86_64.whl

Problem is, command line tells me that:

bash: export: `=': not a valid identifier
bash: export: `https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.11.0rc1-cp35-cp35m-linux_x86_64.whl': not a valid identifier

I just can't find what I've been doing wrong, and now I wonder whether there is some error in the instructions or whether I might have made some really stupid mistake? From what I have read it might be that the usage of export here is wrong, but I'm totally new to Ubuntu and bash shell and what I read there was ambiguous.
