If you&#39;re using Python 2.7 you must install this module : 

    pip install futures

Futures feature has never included in Python 2.x core. However, it&#39;s present in Python 3.x since Python 3.2.

I&#39;m using [Requests][1] to upload a PDF to an API. It is stored as &quot;response&quot; below. I&#39;m trying to write that out to Excel.

    import requests

    files = {&#39;f&#39;: (&#39;1.pdf&#39;, open(&#39;1.pdf&#39;, &#39;rb&#39;))}
    response = requests.post(&quot;https://pdftables.com/api?&amp;format=xlsx-single&quot;,files=files)
    response.raise_for_status() # ensure we notice bad responses
    file = open(&quot;out.xls&quot;, &quot;w&quot;)
    file.write(response)
    file.close()

I&#39;m getting the error:

    file.write(response)
    TypeError: expected a character buffer object

reactjs - how to set inline style of backgroundcolor?

I have followed the procedure given in https://stackoverflow.com/questions/20112989/how-to-use-valgrind-with-python for checking memory leaks in my python code. 

I have my python source under the path

    /root/Test/ACD/atech

I have given above path in `PYTHONPATH`. Everything is working fine if I run the code with default python binary, located under `/usr/bin/`. 
I need to run the code with the python binary I have build manually which is located under

    /home/abcd/workspace/python/bin/python

Then I am getting the following error 

    from concurrent.futures.process import ProcessPoolExecutor
    ImportError: No module named concurrent.futures.process

How can I solve this?

I am novice to Python and following a tutorial. There is an example of `list` in the tutorial :

    example = list(&#39;easyhoss&#39;)
Now, In tutorial, `example= [&#39;e&#39;,&#39;a&#39;,...,&#39;s&#39;]`. But in my case I am getting following error:

    &gt;&gt;&gt; example = list(&#39;easyhoss&#39;)
    Traceback (most recent call last):
      File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
    TypeError: &#39;list&#39; object is not callable

Please tell me where I am wrong. I searched SO [this][1] but it is different.

How can I remove duplicate rows of a 2 dimensional `numpy` array?

    data = np.array([[1,8,3,3,4],
                     [1,8,9,9,4],
                     [1,8,3,3,4]])

The answer should be as follows:

    ans = array([[1,8,3,3,4],
                 [1,8,9,9,4]])

If there are two rows that are the same, then I would like to remove one &quot;duplicate&quot; row.

How to return `False` if all elements are in a list are `False`?

The given list is:

    data = [False, False, False]

I used `Counter` on a list to compute this variable:

    final = Counter(event_container)

print final gives:

    Counter({&#39;fb_view_listing&#39;: 76, &#39;fb_homescreen&#39;: 63, &#39;rt_view_listing&#39;: 50, &#39;rt_home_start_app&#39;: 46, &#39;fb_view_wishlist&#39;: 39, &#39;fb_view_product&#39;: 37, &#39;fb_search&#39;: 29, &#39;rt_view_product&#39;: 23, &#39;fb_view_cart&#39;: 22, &#39;rt_search&#39;: 12, &#39;rt_view_cart&#39;: 12, &#39;add_to_cart&#39;: 2, &#39;create_campaign&#39;: 1, &#39;fb_connect&#39;: 1, &#39;sale&#39;: 1, &#39;guest_sale&#39;: 1, &#39;remove_from_cart&#39;: 1, &#39;rt_transaction_confirmation&#39;: 1, &#39;login&#39;: 1})

Now I want to convert `final` into a Pandas `DataFrame`, but when I&#39;m doing:

    final_df = pd.DataFrame(final)

but I got an error.

I guess final is not a proper dictionary, so how can I convert `final` to a dictionary? Or is it an other way to convert `final` to a `DataFrame`?

I have a python project (which I run within a virtualenv) and that has the following structure:

    Project
    ├───.git
    ├───venv
    └───src
        ├───__init__.py
        ├───mymodules
        │   ├───__init__.py
        │   ├───module1.py
        │   └───module2.py
        └───scripts
            ├───__init__.py
            └───script.py

script.py

    import src.mymodules.module1
    ...

---------

I run the project with venv activated and from the Project directory using the following command:

    (venv)$ python src/scripts/script.py

The script runs but gives out the following error before exiting:

    Traceback (most recent call last):
      File &quot;src/scripts/script.py&quot;, line 1, in &lt;module&gt;
        import src.mymodules.module1
    ImportError: No module named src.mymodules.module1

I have tried running the python shell and trying to import the module from there and it gave no errors. I have _ _init__.py in every directory within src. Is python considering the working directory to be src/scripts? Why is that happening and how can I make src the working directory if that&#39;s the case?

Python can&#39;t find my module

I have a dynamic libray libtest.dylib that is installed in `/PATH/lib`, and an execution binary, myapp, that uses the dylib installed in `/PATH/bin`. 

I can run `myapp` to find the dylib as follows (https://stackoverflow.com/questions/3146274/is-it-ok-to-use-dyld-library-path-on-mac-os-x-and-whats-the-dynamic-library-s):

    DYLD_LIBRARY_PATH=&quot;/PATH/lib&quot; myapp 

I think I can use `install_name_tool` to update the library and executable so that the library can be found with rpath. I used the hints in this post - https://stackoverflow.com/questions/17202313/how-can-i-specify-the-rpath-in-a-dylib. 

In lib, I executed this command to add rpath.

    install_name_tool -id &quot;@rpath/libtest.dylib&quot; libtest.dylib
    install_name_tool -add_rpath &quot;@executable_path/../lib/&quot; libtest.dylib

In bin, I executed `install_name_tool -add_rpath &quot;@executable_path/../lib/&quot; myapp`.

However, when I executed `myapp` in `bin` directory, I have the error messages.

    dyld: Library not loaded: libtest.dylib
      Referenced from: /PATH/bin/./myapp
      Reason: image not found
    Trace/BPT trap: 5

`otool -l myapp` shows the rpath is correctly updated in myapp.

    Load command 16
              cmd LC_RPATH
          cmdsize 40
             path @executable_path/../lib/ (offset 12)

The same is true with libtest.dylib

    Load command 13
              cmd LC_RPATH
          cmdsize 40
             path @executable_path/../lib/ (offset 12)

What might be wrong? 

## ADDED

Of course, I can use ` cc -install_name` when compile and link time, but I wanted to know how to do the same thing my modifying the generatd dylib and execution binary. 

From the lib:

    cc -install_name &quot;@loader_path/../lib/libtest.dylib&quot; -dynamiclib -o libtest.dylib test.c

Or, the install_name can use @rpath:

    cc -install_name &quot;@rpath/libtest.dylib&quot; -dynamiclib -o libtest.dylib test.c

From the bin:

    cc -I../lib -c main.c
    cc -o main main.o ../lib/libtest.dylib -Wl,-rpath -Wl,@loader_path/../lib

Or just one line:

    cc -I../lib -L../lib -o main main.c -ltest -Wl,-rpath -Wl,@loader_path/../lib

I have recently upgraded to Windows 10 from Windows 8.1.

Now I wanted to set an environment variable for my new installation of Apache Maven.

Each time I created the user variable, things were fine. However, I also need to create the system variable where I will need to append the *bin* directory to the variable that I already create in the user variable to be &quot;path&quot;.

Now, each time I do this, I get an error that says &quot;This environment variable is too large&quot;. As a result of this, I am unable to create the path.

I have attached an image of this error.

Is there a way in Go to combine URL paths similarly as we can do with filepaths using `path.Join()`?

For example see e.g. https://stackoverflow.com/q/13078314/772000. 

When I use `path.Join(&quot;http://foo&quot;, &quot;bar&quot;)`, I get `http:/foo/bar`. 

See in [Golang Playground][1].

I&#39;m having xcode issues when I try to use brew and git:

&gt;xcrun: error: active developer path (&quot;/Applications/Xcode.app/Contents/Developer&quot;) does not exist, use `xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools (or see `man xcode-select`)

I can type xcode-select and it shows that the command exists. When I type `xcode-select -p` it shows:
 
&gt;/Applications/Xcode.app/Contents/Developer

but when I do `which xcode-select`, it gives me:

&gt;/usr/bin/xcode-select

I&#39;ve tried to use the command switch and install again via Apple Developer site but none of these options have work so far... How can I fix this?
