FileNotFoundError from subprocess.Popen(cmd)

[TigerStone93]

Hello.
When I run python runGan.py 1 to test, I encountered the error below.

Testing test case 1
Traceback (most recent call last):
File "runGan.py", line 90, in
mycall(cmd1).communicate()
File "runGan.py", line 21, in mycall

File "C:\Users\user\Anaconda3\envs\tensorflow\lib\subprocess.py", line 1178, in _execute_child
startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

Please give me any solution or hint to solve this problem.

Use python 3.6.7, tensorflow has some problems with python 3.7.

@LukeZhuohuiLi Thanks for your advice but it did not work under Python 3.6.7 too.

@LukeZhuohuiLi Thanks for your advice but it did not work under Python 3.6.7 too.

I got the same problem, I don't remember, but I solved it either switch to python 3.6 or switch python 32bit to 64bit, after that just run pip3 install -r requirements.txt.

@LukeZhuohuiLi Could I ask what environment did you used? Was it Anaconda3(64bit)?

I didn't use Anaconda because downgrading to python 3.6 in Anaconda takes a lot of time. Also CUDA 10.1 is not compatible with pytorch.
Check the right version and command from here: https://pytorch.org

Don't use python 3.7 since tensorflow is not compatible with python 3.7.

also, there is one problem that I can't remember, I ended up using python 3.6.7 64bit(I am sure 3.7 and 3.6.0 doesn't work with the code) and add the Scripts folder to the environment variables(path). update the pip directly from CMD, rename the python.exe to python3.exe.
You will probably need wget.exe download from here, unzip and put it inside the Scripts folder.
Then I use
pip3 install --ignore-installed --upgrade tensorflow-gpu
pip3 install -r requirements.txt

python3 runGan.py 1
You will see a lot of warnings, but the program will still run.
wget.zip

@LukeZhuohuiLi
What a detailed desciption!
Thank you for your help.
I will try and let you know the result.

@LukeZhuohuiLi It works perfectly on Python 3.5, Ubuntu 16.04.
Thank you so much.
Maybe there is a compatibility problem on Anaconda 3, Windows.

including shell=True in subprocess function solved issue for me on win10 inside runGan.py, example line 21: subprocess.Popen(cmd) --> subprocess.Popen(cmd,shell=True)

@EdisonBing Thank you for your kind commentary.
