Check for extra prerequisites

[eohara-ie]

Testing in relatively fresh environment on my Windows PC to check for additional required packages to add to requirements.txt

[eohara-ie]

Getting this error when running pip install -r requirements.txt:

error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft
.com/downloads/

[eohara-ie]

Seems to not affect the notebook so far

[pat42w]

I think it's needed for the pyportfolioopt parts. The DB part should work fine without this. But the solvers used for efficient frontier probably won't work

[eohara-ie]

Yeah pyportfolioopt didn't install as a result

[pat42w]

Just have to call our that visual studio as a pre requisite

[eohara-ie]

Yeah I see it's stated in the pyportfolioopt repo but no harm to emphasise it

[pat42w]

You can take the cattle to water but ya can't make them drink....

[eohara-ie]

I installed the C++ Build Tools as instructed in https://github.com/robertmartin8/PyPortfolioOpt/blob/master/README.md

Got this error numpy.core.multiarray failed to import which I fixed by updating numpy

Now seeing this

No module named 'plotly'

[eohara-ie]

pip install plotly

fixed that.

Now breaking here

cf.go_offline()

'cf' is not defined

[pat42w]

Please add plotly to the requirements txt

[pat42w]

I think you can comment out the CF line which notebook is that in

[eohara-ie]

V1

[pat42w]

Removed cf references from the files as it is not used anywhere, we can add the note: error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft .com/downloads/ to the readme but its fairly self explandatory from the pyportfolioopt error

[eohara-ie]

I think no harm to have it in pre-reqs section of the README Idiot-proof it

[eohara-ie]

Closing for now
