I want to use 2D Liquid simulator with cellular automaton in Godot Engine (GDNative / C++) for my project.
I followed guide to compile and add the plugin to a new Godot engine project. After compiling godot-cpp binary (platform=windows) I have no .dll file and no bin/lib/ that are needed for the next step.
I tried to do it with both "original" version and "default" version of the plugin from the guide. Both times running into the same issue:
$ scons platform=windows
scons: Reading SConscript files ...
scons: *** Path for option target_path does not exist: bin/lib/
File "C:\Users\nkilaru\Documents\liquid-simulator-godot\SConstruct", line 27, in <module>
line 27 in SConstruct:
# Updates the environment with the option variables.
opts.Update(env)
I am obviously doing something wrong... Does anyone know what is the problem and how to solve it?
I'm trying to run a code as described here.
I have a anaconda enviroment with tensorflow installed via pip installation.
When trying to run the example on the link provided I have a issue. The first one was that the file:ptb_word_lm.py wasn't present on my installation. I just copied the file from github and tried to run anyway. I got the following error when running python ptb_word_lm.py --data_path=/tmp/simple-examples/data/ --model small
error message:

I have found people on google suggesting to change the line from tensorflow.models.rnn.ptb import reader to just import reader, but it doesn't seem to work for me.
Does anyone know the possible solution?

I spent a lot of time debugging warnings and seems scons 1.3.1 doesn't support visual studio 2015, however google's build
instructions imply opposite. Also it's not fully clear whether the error depends on the warnings. Please help to solve the issue.
I solved the issue, turns out a new version of wix toolset has bin folder with all the utils and official docs and tutorial contains wrong environment variable. By the way the warnings have no impact on build process at all.
So probably there is no point to debug any code in similar situations, just need to check the environment.
I had already had sublime and when setting up new plug-ins, I found problem for the setup of SublimeClang. It requires libClang but I searched all my folders using the " locate clang" command and couln't find libclang at last (The doc on the web said it should be located in usr/lib/x86_64-linux-gnu/).
When i open the sublime, the console printed out like this:
Traceback (most recent call last):

error: It looks like libclang.so couldn't be loaded. You have to compile it yourself, or download from https://github.com/quarnster/SublimeClang/downloads.
Please note that this plugin uses features from clang 3.0 so make sure that is the version you have installed.
Once you have the file, you need to copy libclang.so into the root of this plugin. See http://github.com/quarnster/SublimeClang for more details.
I'm rookie in ubuntu OS and hope someone can give me help. Many thanks!
I cannot successfully run the first command in the Scrapy tutorial (http://doc.scrapy.org/en/latest/intro/tutorial.html). The code copy pasted below is the result (with the error at the end).
Python 2.7 is installed, and I followed the installation instructions for scrapy (http://doc.scrapy.org/en/latest/intro/install.html). I am running Python 2.7.6 32 bit on Windows 7 (64 bit).

Scrapy-0.22.2-py2.7

I just reinstall cryptography to make it work.
pip uninstall cryptography
pip install cryptography
I had this problem due to another (older?) version of libeay32.dll and ssleay32.dll being on the PATH before those of my own OpenSSL 1.0.1g installation. I recommend you use Process Monitor from SysInternals to monitor python.exe to see where it is actually loading your OpenSSL DLLs from.
In my case, the offender was some Intel components at C:\Program Files (x86)\Intel\iCLS Client\ that came with my drivers. After moving my own OpenSSL bin directory earlier in the PATH environment variable, everything worked as expected.
this is due to _Cryptography_cffi_48bbf0ebx93c91939.pyd depends on openssl dll ssleay32.dll and libeay32.dll. after you compile openssl on windows, u can copy these 2 files to system32.
#crazyzh1984's method is a little complex, but his supplement that posted at the bottom of his answer is very useful. I download the "Win32 OpenSSL v1.0.1g Light" at http://slproweb.com/products/Win32OpenSSL.html and then I could install pyOpenSSL successfully.
#lambokini is right，but i'cant comment on the answer, so come this one.
First download openssl source from http://www.openssl.org/
Second start "Visual Studio Command Prompt", compile and install openssl follow install guide(INSTALL.W32 or INSTALL.W64).
Then add "[openssl install path]\bin" to the environment variable "path",
and you can delete ssleay32.dll and libeay32.dll under system32.
Notice: dll will be load from the first place it seached.
for exmple: Path=xxx;d:\PHP5;d:\openssl\bin;
if ssleay32.dll and libeay32.dll also appears under PHP5,
then python will load that one.
I'll write my own take on this due to my extreme frustration and hopes that this might help some other poor chap with his issues getting scrapy to work on windows..
Had a similar issues with faulty libeay32.dll and ssleay32.dll, or so it would seem, but confirmed it with Process Monitor.
It all went to hell after those dll's were found in System32:
So i wasnt suffering from wrong PATHs (but i did change their order so system32 comes before C:\Program Files (x86)\Intel\iCLS Client\.
Next i used this site the other guys here pointed to. Ive used Win32 OpenSSL v1.0.2j Light, since the newer one (1.1.0b) didnt generate these dlls for me for some reason.
Generate them in a different bin folder so you see they are new, and then copy them to system32. Voila, scrapy command line works.
Also, as of today, anaconda's scrapy 1.1.2 does not create a key file for running scrapy commands, ive opened and closed a question about this issue here.
As others have said above, there are two .dll files that are loaded instead of the openssl that is downloaded with Scrapy. Those two .dll files are not compatible.
I resolved this by placing the downloaded .dll files (i used Anaconda to install scrapy) as a higher priority in the Environment Variables as shown in the attached image.
In Environment Variables, within System Variables and the "Path" i placed the Anaconda3 location as shown above at the top and therefore makes it the priority when python comes to load openssl
As already mentioned in the other answers, the issue is caused by the two files ssleay32.dll and libeay32.dll.
The error occurred when importing OpenSSL in Python
>>> from OpenSSL import crypto, SSL
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "c:\Python27\lib\site-packages\OpenSSL\__init__.py", line 8, in <module>

ImportError: DLL load failed: The operating system cannot run %1.
Here's how I solved the issue on Windows 10. If you have git for Windows (download here) you can just copy these two files from Git\mingw64\bin\ to some location in your path. What worked for me was to copy them to c:\Windows (or else to the folder from which you're starting Python).
To find the locations of the dll files type at a cmd prompt:
>where libeay32.dll
C:\Program Files (x86)\Intel\TXE Components\TCS\libeay32.dll
...
C:\Users\me\AppData\Local\Programs\Git\mingw64\bin\libeay32.dll
I ran across this error today on a Windows 7 system. The problem for me was similar to #user2314737, #voetsjoeba, and #Olegp. libeay32.dll and ssleay32.dll where in folders related to Intel that were in the Windows path environmental variable.
Unfortunately, my system is locked (work computer), so I could not move the files or alter the system's path variable. Instead, I manually removed the Intel related items from the path variable that Python accesses using:
import os
os.environ['path'] = ';'.join(
filter(lambda x: 'intel' not in x.lower(), os.environ['path'].split(';'))
)
import OpenSSL
