pip install theano on virtualenv python unicode related error

Question

Recently, I tried to install theano on virtualenv without sudo permission. I met a lot of problems and I solved most of them with the help of SO. However, I have no idea how to solve the last one. But I think it's important to put my entire procedure here since it's not that many. I really wish someone can tell me where goes wrong.

First I download a python-2.7.3.tar.gz file, extract it and try to install python with

./configure --prefix=$HOME --enable-shared && make && make install

but there will be a problem when I try to create a virtual machine:

undefined symbol: PyUnicodeUCS2_Replace

So, with the help of this SO post, I remove all the files in lib/, bin/ and include/ and tried the following command:

./configure --prefix=$HOME --enable-shared --enable-unicode=ucs4 && make && make install

Then I tried to create a virtual machine with this command:

python virtualenv-1.10/virtualenv.py -p /afs/cs.cmu.edu/usr/haohanw/bin/python --no-site-packages --distribute test

And virtual machine works.
(P.S. if I use Python-2.7.8 or Python-2.7.7, there will be an error: undefined symbol: _PyLong_AsInt here.)

Then, I activate the virtual machine with source test/bin/activate,
and install numpy first with pip install numpy,
then according to this SO post, I changed some configurations.
According to this SO post, I run pip install --upgrade pip

Now with pip version 1.5.6 and python version 2.7.3, I run pip install scipy and unfortunately got this error:

Traceback (most recent call last):
File "/afs/cs.cmu.edu/user/haohanw/private/deeplearning/test/bin/pip", line 11, in <module>
sys.exit(main())

return command.main(cmd_args)

text = '\n'.join(complete_log)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 72: ordinal not in range(128)

I have been working on it for four days, can someone help me with it?

Thank you so much!

Could you print the whole stack trace error because one line of error statement is not sometimes enough for debugging purposes. — RAM, Oct 07 '14 at 04:01

I think I found the answer. When I create the virtualenv, I should use the python I just compiled, rather than the one that is built in the system. I think they are different because I compiled python with --enable-unicode=ucs4

Also found the fact that `sudo` can properly avoid this problem, but no idea way – Haohan Wang May 14 '15 at 21:42
