Spyder external system terminal does not work (Python3.6) - python-3.x

I am not sure if this is a right place to ask this type of questions. I am a python beginner or programmer overall at this point. I am using Spyder to use python 3.6 (via Anaconda). I wrote a code that works fine when I run it in the current Ipython console. But I really need to run it in an external system terminal. In order to do so, I chose the following path: Run-> configuration per file -> execute in an external system terminal. That has been working fine. But now it refuses to work!
I validated that there is nothing wrong with my code by running something simple and saw that running via external system terminal does not work.
So far I deleted Anaconda and re-installed it. Could someone suggest what I should be looking for to diagnose the problem and fix it?
Thanks!

I had the same problem and noticed that unless the Working directory settings is set to "The directory of the file being executed", it won't work.
You can change it in "Run" > "Run configuration per file".

Anaconda Navigator does not open (Windows 10)

I just downloaded and installed Anaconda3 on windows 10 platform.
Apparently, the installation process finished successfully however I can't open Anaconda Navigator.
What I'm doing is just clicking on "Anaconda Navigator" icon from start menu.
After a while an empty console window pops up twice, then it desappears immediately without showing an error message and nothing seems to happen after that.
I've been reading about similar errors and found out that running this command, conda update --all might solve the problem.
I tried it out, but ended up getting a network connection problem for a particular URL.
But my internet connection is working fine since I'm actually able to access that URL from the browser and get a response.
It's worth mentioning that I've already uninstall Anaconda3 and set up the following user environment variables.
Any help would be appreciated, thanks in advance!
Finally found a solution to this problem, I recommend you to read the official documentation and follow the steps described there in order to make sure everything was installed correctly.
Check out this article:
https://docs.anaconda.com/anaconda/install/verify-install/
After trying to starting up Anaconda Navigator from the console I got this specific error that helped me to get a final solution.
Basically I just had to move some files within anaconda3 installation folder from one path to another.
Navigate to %ANACONDA_HOME%\Library\bin, there you will find the files listed below
libcrypto-1_1-x64.dll
libcrypto-1_1-x64.pdb
libssl-1_1-x64.dll
libssl-1_1-x64.pdb
So, just move them to this path: %ANACONDA_HOME%\DLLs
Give it a try one more time and you will be able to run it.
Note:
%ANACONDA_HOME% refers to Anaconda3 installation folder in your computer.

How to reconfigure VSCode for python

I had configured VSCode for python, it was working fine, linter , autopep all the things were working fine. After some days I installed Anaconda, from here problems started, after this I got error that Select Python Interpreter at the bottom of VSCode, I added python path to the settings,then it works fine but "Select Python Interpreter" error was still coming. Some days before I installed Javascript extension, after this linter,autopep nothing is working,only using python command line python program is getting run.
I removed javascript extension,again installed VSCode, now the things are worst,nothing is working now.Please anyone help me to how to reconfigure VSCode to work properly.Even I removed Anaconda installation too, still problems not solved. I searched online but did not get any proper inforamtion.
I had a similar issue, I think you have both Python 3.7 and Anaconda installed separately, Use any one them , remove the other. When both of them is together it was throwing lot of issues. I would prefer to remove Anaconda(pure personal choice).If you don't have much customized settings in VScode, delete its user configuration files and set it up again. it will work

Anaconda Prompt(Anaconda3) does not recognize files in a directory

I took to heart the message that support for anaconda2 was dropped. I installed anaconda3 and used 2to3 to convert my *.py codes. Everything seemed to work as expected. I have several 2 line bat codes that cd to a particular directory and then call python to execute a particular *.py code in that directory. By loading Anaconda Prompt(Anaconda3) and invoking the bat file I could run pythons in that directory as expected.
Then, a couple of days ago, I made such a run and got an error message saying the *.py file could not be found. I immediately looked in the directory and the python file was there as expected. I then did a dir command in Anaconda Prompt(Anaconda3) and found that almost no files in the directory were listed. This was happening on my windows 10 laptop.
On my desktop, everything continues to work as expected. Are there any suggestions as to what could cause such a problem and how to fix it.
Thanks,

Responding to the request for additional information, I have a bin directory that is in path. In bin\MackData.bat is
c:
cd %USERPROFILE%\Documents\Medev\MackData
copy sugarhist.png sugarhist.old.png
python MackData.py
When I open Anaconda Prompt(Anaconda3) and enter MackData I get
(base) C:\Users\Mack>MackData
(base) C:\Users\Mack>c:
(base) C:\Users\Mack>cd C:\Users\Mack\Documents\Medev\MackData
(base) C:\Users\Mack\Documents\Medev\MackData>copy sugarhist.png sugarhist.old.png
1 file(s) copied.
(base) C:\Users\Mack\Documents\Medev\MackData>python MackData.py
python: can't open file 'MackData.py': [Errno 2] No such file or directory
(base) C:\Users\Mack\Documents\Medev\MackData>
But MackData.py is a python file in the directory MackData.
This code worked on this laptop until a few days ago and continues to work on my desktop computer. I can, of course, publish MackData.py but that seems irrelevant. The point is that Anaconda can't find it.
Thanks,
Mack
I must submit a sincere apology to this community. I have determined my problem and Anaconda is not responsible in any way. I thank all of you for you concerns and comments.
For any who might be interested I will give a brief outline of what happened. First, I installed Anaconda3. Several days later my directory, MackData, was moved to a new location. I conjecture that happened by me inadvertently letting my hand drag on the touch pad. Then, not knowing the location had changed I updated my laptop from my desktop. My update program not finding MackData where expected recreated it and put only the most recently changed files from the desktop into the new MackData. New but in the correct location. Then of course running my script in the Anaconda3 prompt failed. Doing a dir in the Anaconda3 prompt showed only a few files were there. I then went to Windows File Explore and looked at MackData and saw all of the expected files. I used the quick access feature which unknown to me pointed to the old directory in its new location.
That is not intended to be an excuse but only as an explanation. Again, I do apologize to the community.

I'm pretty sure newer anaconda launchers users different environment paths, and not even windows ones.
I suggest either checking the environment path within the anaconda launcher and configurations or, a better solution in my opinion, run these scrips using the regular python engine, without using anaconda (simpler, more determinant and works within your standard environment)

Pycharm tensorflow ImportError but works fine with Terminal

I made a virtualenv with tensorflow installed and I changed Python interpreter set to the location where the virtualenv is located at. When I ran the program, it gives the error:
ImportError: libcudnn.so.5: cannot open shared object file: No such file or directory
I have the following lines written in my .bashrc file
export CUDA_HOME=/usr/local/cuda-8.0
export LD_LIBRARY_PATH=${CUDA_HOME}/lib64:$LD_LIBRARY_PATH
export PATH=${CUDA_HOME}/bin:${PATH}
Also, I found the libcudnn.so.5 file in the following path:
/usr/local/cuda-8.0/lib64
I encountered this error before I opened PyCharm and I did manage to install the correct cudnn version. The problem is, I can use
$ source [virtualenv_path]
to active the virtualenv and run python in terminal and everything works fine, no errors shown. The program also runs without error in Pycharm's terminal but it just gives me the above error whenever I click the run button. Could there still be something wrong with the environment variable? How do I fix it?
Unfortunately in pycharm you have to set CUDA_HOME and LD_LIBRARY_PATH inside the IDE. To do that go to the Run menu->edit configurations then choose your project. Then you click on the Environment Variables and add an entry for CUDA_HOME and LD_LIBRARY_PATH. When you have done that you can run directly from inside pycharm. I would also recommend setting the defaults to have these paths as well, so you don't have to do this for every project. Also it wouldn't hurt to make sure you have the interpreter from source [virtualenv_path] set while you are on this setting page. Let me know if you have trouble finding where to do this.
I've read this other Stackoverflow post: Pycharm environment different than command line, and it seems that the problem is that openning PyCharm in the normal way won't preserve the bash environment. The solution is to open PyCharm from the command line and everything works now. All you need to do is to open PyCharm using charm and everything works fine now.
I have searched a lot, but I didn't find the right solution for this question anywhere. I found the solution with my friends and I would like to share with you also.
If your Tensorflow works in terminal properly but doesn't work in Pycharm you have two solutions:
1- Open Pycharm from Terminal. For me:
pycharm-community
2- If you are using Unity, you need to edit .profile, because Pycharm doesn't preserve .bashrc: So, open a terminal and type:
gedit .profile
Then, add the following codes at the end of the opened file:
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
Save and exit. Now, you can work with Tensorflow in Pycharm without the necessity of opening the Pycharm form terminal.

Error in using 'theano-nose' command

After installing Theano from Enthought Canopy on Windows, following the steps here: http://deeplearning.net/software/theano/install.html#id9 , I tried to execute the command theano-nose from Canopy terminal. I got an error message saying "unable to find theano-nose". Can someone tell me what might be going wrong?
theano-nose is from the command line. But your shell need to be able to find it.
It is highly possible it didn't got installed correctly on Windows or that you need to reboot or log out/log in. I do not remember Windows particularities on that level.
But a simple work around is to start python and run this:
import theano
theano.test()
This is equivalent for what you want to do.
