Dmitry's response didn't work for me. 

I got mine working by going to Project Interpreters, Selecting the "Paths" tab, and hitting the refresh button in that submenu. It auto-populated with something called "python-skeletons".

You have to mark your root directory as:
<code>SOURCE ROOT</code> (red),
and your applications:
<code>EXCLUDED ROOT</code> (blue).
Then the unresolved reference will disappear. If you use PyChram pro it do this for you automatically.

I find myself removing and re-adding the remote interpreter to fix this problem when Invalidating Caches or Refreshing Paths does not work.

I use vagrant and every once and awhile if I add a new VM to my multi-vm setup, the forwarded port changes and this seems to confuse PyCharm when it tries to use the wrong port for SSH. Changing the port doesn't seem to help the broken references.

Sorry to bump this question, however I have an important update to make.

You may also want to revert your project interpreter to to Python 2.7.6 if you're using any other version than that This worked for me on my Ubuntu installation of PyCharm 4.04 professional after none of the other recommendations solved my problem.

&gt; Apply &gt; Set your python interpreter again &gt; Click Apply

Profit - Pycharm is updating skeletons and everything is fine.

entityMap|blocks|key|1hkl5|text|您可以尝试关闭Pycharm，删除|type|unstyled|depth|inlineStyleRanges|entityRanges|data|fttsp|文件夹中，然后再次启动Pycharm并重新创建项目。这对我来说是有效的，而无效缓存则不起作用。^0|0^^$0|$]|1|@$2|3|4|5|6|7|8|E|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|F|9|@]|A|@]|B|$]]]]

You might try closing Pycharm, deleting the <code>.idea</code> folder from your project, then starting Pycharm again and recreating the project. This worked for me whereas invalidating cache did not.

I finally got this working after none of the proposed solutions worked for me. I was playing with a django rest framework project and was using a virtualenv I had setup with it. I was able to get Pycharm fixed by marking the root folder as the sources root, but then django's server would throw resolve exceptions. So one would work when the other wouldn't and vice versa. 

Ultimately I just had to mark the subfolder as the sources root in pycharm. So my structure was like this

<pre><code>-playground
 -env
 -playground
</code></pre>

That second playground folder is the one I had to mark as the sources root for everything to work as expected. That didn't present any issues for my scenario so it was a workable solution. 

Just thought I'd share in case someone else can use it.

In my case the inspection error shows up due to a very specific case of python code. 
A min function that contains two numpy functions and two list accesses makes my code inspection give this kind of errors. 

Removing the 'd=0' line in the following example gives an unresolved reference error as expected, but readding doesn't make the error go away for the code inspector. I can still execute the code without problems afterwards.

<pre><code>import numpy as np
def strange(S, T, U, V):
 d = 0
 print min(np.abs(S[d]), np.abs(T[d]), U[d], V[d])
</code></pre>

Clearing caches and reloading list of paths doesn't work. Only altering the code with one of the following example patches does work:

<ul>
<li>Another ordering of the 'min' parameters: schematically S U T V but not S T U V or T S U V</li>
<li>Using a method instead of the function: S[d].abs() instead of np.abs(S[d])</li>
<li>Using the built-in abs() function</li>
<li>Adding a number to a parameter of choice: U[d] + 0.</li>
</ul>

My problem is that Flask-WTF is not resolved by PyCharm. I have tried to re-install and then install or Invalidate Cache and Restart PyCharm, but it's still not working.

Then I came up with this solution and it works perfectly for me.

<ol>
<li>Open Project Interpreter by Ctrl+Alt+S (Windows) and then click Install (+) a new packgage.</li>
</ol>

<a href="https://i.stack.imgur.com/myuCX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/myuCX.png" alt="enter image description here"></a>

<ol start="2">
<li>Type the package which is not resolved by PyCharm and then click Install Package. Then click OK.</li>
</ol>

Now, you'll see your library has been resolved.

If you are using <code>vagrant</code> the error can be caused by wrong python interpreter.
In our <code>vagrant</code> we are using <code>pyenv</code> so I had to change <code>Python Interpreter path</code> path from <code>/usr/bin/python</code> to <code>/home/vagrant/.pyenv/versions/vagrant/bin/python</code>

@kelorek works for me, but before, in interpereter paths I had to add some path.
lets say
<pre><code>from geometry_msgs.msg import Twist
</code></pre>
is underline as error, then in remote machine in python run:
<pre><code>help(&quot;geometry_msgs&quot;)
</code></pre>
at the end there will be path lets say :
<pre><code>/opt/ros/foxy/lib/python3.8/site-packages/geometry_msgs/__init__.py
</code></pre>
so to Your intepreter pycharm path add
<pre><code>/opt/ros/foxy/lib/python3.8/site-packages
</code></pre>
Hope it will help You and it helps me :)

Are you using virtualenv?

if so, you need to notify PyCharm for every change in the location of the the desired python.exe (merely ./activate is not enough for PyCharm)

Make sure Pycharm points to the correct interpetor and packages:
File -> Settings -> Project -> Project Interpreter. Click the gear and choose python.exe under virtualenv's Scripts folder

I am using PyCharm to work on a project. The project is opened and configured with an interpreter, and can run successfully. The remote interpreter paths are mapped properly. This seems to be the correct configuration, but PyCharm is highlighting my valid code with "unresolved reference" errors, even for built-in Python functions. Why don't these seem to be detected, even though the code runs? Is there any way to get PyCharm to recognize these correctly?

<hr>

This specific instance of the problem is with a remote interpreter, but the problem appears on local interpreters as well.

 我正在使用PyCharm处理一个项目。项目已打开并配置了解释器，可以成功运行。远程解释器路径已正确映射。这似乎是正确的配置，但是PyCharm使用“未解决的引用”错误来突出显示我的有效代码，即使对于内置的Python函数也是如此。为什么即使代码运行，这些似乎也没有被检测到？有没有办法让PyCharm正确识别这些？ 这个问题的具体实例是远程解释器，但问题也出现在本地解释器上。
