FileNotFoundError: [Errno 2] No such file or directory: 'python': 'python' while running a python script

While trying to run a python script on EC2 (running ubuntu), I'm getting this error:
Traceback (most recent call last):
File "128d.py", line 9, in <module>
"--pca_params", "./vggish_pca_params.npz"])
File "/usr/lib/python3.6/subprocess.py", line 267, in call
with Popen(*popenargs, **kwargs) as p:
File "/usr/lib/python3.6/subprocess.py", line 709, in __init__

raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'python': 'python'
All the dependencies are installed. I've tested the script on my home machine (Windows 10), and it works just fine. I can see that something is wrong with python installed on the EC2 machine, probably. But I didn't manage to find an answer on the web.

I've fixed the problem.
Turns out, I had my python installed in a folder that was named python3. So, when the suprocess.py file tried to find python in path, it wasn't there.
I've renamed python3 in /usr/bin/ to python and the problem is fixed.
P.S. However, keep in mind, that it might raise some other issues. When I tried to aws s3 cp, it was looking for python3 instead. Maybe adding another copy of that folder as python3 would help.

getting gmsh into the virtualenv

I'm extremely new to Python, so sorry if this is a stupid question. Anyways, I'm getting this error when trying to run a package I installed on PyCharm (Python IDE):
Traceback (most recent call last):

FileNotFoundError: [WinError 2] The system cannot find the file specified
From what I've gathered from previous questions, it seems this is because I don't have gmsh in my virtualenv. Now that I've downloaded gmsh, I can't find a proper installation guide on how to get it into the virtualenv. Does anyone have experience with this?
I guess more specifically, is there a way I can pinpoint the path that it's trying to access and just paste gmsh into that directory?

openbte\geometry.py seems to run gmsh.exe without any path:
a=subprocess.check_output(['gmsh','-' + str(self.dim),'mesh.geo','-o','mesh.msh'])
Which means it expects gmsh.exe somewhere in the %PATH%. So install gmsh and add the directory with gmsh.exe to the %PATH%.

Python error: missing 'mdb-schema' when using python_access package

Running on Ubuntu 16.04, Python 3.6.2
I have successfully used this package before. In fact, it works on a different pc but not the one I need it to work on.
https://pypi.python.org/pypi/pandas_access

The code for pandas_access is available here
https://github.com/jbn/pandas_access/blob/master/pandas_access/init.py
It's supposed to only require MDB Tools which I have installed and it works. I can open the access database using MDB Tools on its own.

Solved!
I ran mdb-schema on the command line of the working pc and got:
Usage: mdb-schema [options] []
where options are:
-T Only create schema for named table
-N Prefix identifiers with namespace
I rant mdb-schema on the non-working pc and got:
The program 'mdb-schema' is currently not installed. You can install it by typing:
sudo apt install mdbtools
Not sure how I this wasn't installed as I was running gmdb2 on it for sure before this but oh well, need to move on.

I had this error and installing GDAL through Homebrew fixed this for me. Installing the the binaries for GDAL didn't correct the error but once I installed through brew it was resolved.
brew install gdal
seems like the same issue as here: Python GDAL: pip install --no-install GDAL fails
If you've already installed the binaries (like I had) then this answer worked for me: https://stackoverflow.com/a/44051123/3969685

This simple procedure seemed to work for me on MAC sierra, python 3.6, GDAL 2.2.3
1) Install GDAL framework using dmg installer for MAC [GDAL MAC
Frameworks]: http://www.kyngchaos.com/software/frameworks
2) Add gdal-config folder to your path and get your version:
$ export PATH=/Library/Frameworks/GDAL.framework/Versions/2.2/Programs:$PATH
$ gdal-config --version
3) Use pip to install the version reported by gdal-config --version:
$ pip install gdal==2.2.3
Step 1 Seems to set up the python site-packages under its install framework folders and I think you could copy them to your python site-packages. But better to use pip install.

This simple procedure seemed to work for me on MAC
Install GDAL framework using Brew
> brew install gdal
gdal-config --version
gdal-config --version
2.4.4
3. GDAL Python binding
pip3 install gdal==2.4.4
Note the GDAL version of the end of the command, it must be the same as the obtained in the step above using gdal-config. To avoid conflicts or any further issues, it’s important to install and use the exact versions that any component will require.

Install TurboGears on windows xp

I've been trying to get TurboGears installed on Windows by following this site.
I've installed virtualenv but when I execute the command "virtualenv --no-site-packages testproj", I get the following message:

Can someone help me debug this ? If any one knows a better tutorial to install turbogears, please let me know.

I figured out the error. Apparently, virtualenv does not like it if folder names have spaces (eg Documents and Settings). It worked fine when my folder names had no spaces.
