Need to run make install inside Docker container before we can run examples

[wangkuiyi]

Users must run make install as follows:

git clone https://github.com/paddlepaddle/paddle
cd paddle
docker build -t paddle:dev .
mkdir build
nvidia-docker run --rm -it -v $PWD:/paddle paddle:dev /bin/bash
$ cd /paddle/build
$ cmake ..
$ make -j56

After doing the above steps, we should have a built binary version of PaddlePaddle in ./paddle/build, or /paddle/build in the container. I suppose that in the container, we should be able to run

$ python python/tests/book/test_fit_a_line.py

However, if I do so, Python would complain that it cannot import paddle.

It seems that we must run make install after make so could we run examples. This doesn't make sense.

Before run the test, we need install the generated "whl" package using " pip install", the package is located in the "build/python/dist" directory.

Got it. Thanks.

Is it possible that we don't run pip install (nor make install), but can import paddle from Python?

I am closing this issue, and leave the question in a new issue.
