issues installing Lasagne

[asimkievich]

Hi there, this is a response to #16, below is your recommendation.

I face the following issue while installing the requirements below:

Help is much appreciated! Thanks so much in advance!

note: directory c:\Windows\System32\src\lasagne does not exist. also, I tried creating the directory and the results are the same

Make sure that you've got the right versions of Lasagne and nolearn installed. These have changed since the first version of the tutorial.

pip install -U -r https://raw.githubusercontent.com/dnouri/kfkd-tutorial/master/requirements.txt Alternatively, and maybe better if you're using Conda:

pip uninstall Lasagne pip uninstall nolearn pip install -r https://raw.githubusercontent.com/dnouri/kfkd-tutorial/master/requirements.txt Related: #13

I've never seen this particular problem before but it looks like uninstalling Lasagne before installing might fix it: pip uninstall Lasagne

you are the man Daniel! it worked. thanks a lot.

btw, I get this thread: WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.

not sure if it is a bogus message or for real. execution takes forever (when compared with previous implementation). Thanks!

I am sorry, it appears that there was no g++ compiler or that the environment variable did not point to the correct bin directory. I corrected that and get the error below.

I posted a question on stackoverflow but if you happen to know the answer and post it, I will really appreciate it. Thanks again!

Your last error doesn't look like it's specific to Lasagne or nolearn. Best to Google for the error message, or ask on the Theano mailing list.

Hi Daniel, agree.

However, since lasagne / nolearn depend on theano to run - and since I found a solution - I thought I might as well post a link to the issues I created on theano (solution included). Thanks a lot for your help with the other issues. Best,

Alex

Hi Daniel, Your tutorial on Kaggle landmark detection was awesome. I learnt Lasagne step-by-step from that page. I have a practical question when I want to scale up to datasets such as ImageNet. As you are aware, in ImageNet, images are stored under folders such as 'n1', 'n2', with each folder containing about 700-800 images. In your tutorial, we usually load data into variables X and y. But, do you think such huge data can be loaded at once into X. I also have a image regression task. Each original image, I crop to 256X256 and create a heat-map image of 64X64.

Can you suggest a procedure to deal with such large datasets.
