随便写写 (1)

 我又生病了,最近病毒施虐,倒霉的我又感冒了。 


不过看了一部好电影,每次想起就会生出勇气。 明天会更好。 、

父亲希望你去欧米茄星,我们也希望你能去,因为那也是我们的愿望,希望你能代我们实现!

曾经我也是全村的希望,村里的小孩只有我上了大学,我要成为大学的教授,去帮同年的小伙伴实现成功的愿望,用我的眼睛,去帮大家看世界。不过前路如何艰难,我也要坚持下去。加油kiwi.

冯仑说:伟大都是熬出来的。为什么用熬?因为普通人承受不了的委屈你得承受,普通人需要别人理解安慰励,但你没有,普通人用对抗消极指责来发泄情绪,但你必须看到爱和光,在任何事情上学会转化消化,普通人需要一个肩膀在脆弱的时候靠一靠,而你就是别人依靠的肩膀

geomagic

 Spent one hour on repair geometry in the geomagic, 


rule of thumb

1. flip to the same normal before moving the imported item 

2. then connect them using bridget


3. easy

tensorflow error

 https://github.com/tensorflow/tensorflow/issues/35403#


using a tf.Tensor as a Python bool is not allowed in Graph execution. Use Eager execution or decorate this function with 


I solve it by just using Can you please try with !pip install tensorflow-gpu==2.1-rc2and see if the error still persists. I am not seeing any issue with TF 2.1.Thanks!

compiling netflow

 Have some problem on compiling netflow, so I think the error resulted by 


https://stackoverflow.com/questions/10727568/cannot-convert-parameter-1-from-const-char-to-lpcwstr


n your project, it sounds like all of these macros are referencing the -W versions. This is controlled by the UNICODE preprocessor macro (which is defined if you choose the "Use Unicode Character Set" project option in Visual Studio). (Some of Microsoft's C and C++ run time library functions also have ANSI and wide versions. Which one you get is selected by the similarly-named _UNICODE macro that is also defined by that Visual Studio project setting.)

Typically, both of the -A and -W functions exist in the libraries and are available, even if your application is compiled for Unicode. (There are exceptions; some newer functions are available only in "wide" versions.)

If you have a char * that contains text in the proper ANSI code page, you can call the -A version explicitly (e.g., SetWindowTextA). The -A versions are typically wrappers that make wide character copies of the string parameters and pass control to the -W versions.

An alternative is to make your own wide character copies of the strings. You can do this with MultiByteToWideChar. Calling it can be tricky, because you have to manage the buffers. If you can get away with calling the -A version directly, that's generally simpler and already tested. But if your char * string is using UTF-8 or any encoding other than the user's current ANSI code page, you should do the conversion yourself


change Unicode fixed the problem

tensorflow issue

 stuck in tensorflow for few days for PINN. 

One of thing to get rid of placeholder is upgrade tensorflow

import tensorflow.compat.v1 as tf

tf.disable_v2_behavior() 

#tf.compat.v1.disable_eager_execution()

stop at here 

File "C:\Users\Chiwei\Anaconda3\lib\site-packages\tensorflow\python\framework\ops.py", line 481, in _disallow_in_graph_mode

    " this function with @tf.function.".format(task))


OperatorNotAllowedInGraphError: using a `tf.Tensor` as a Python `bool` is not allowed in Graph execution. Use Eager execution or decorate this function with @tf.function.


suspect is the save function and gpu plot will come back later.

editing mesh in comsol

 hahahahaha I finally solve the problem in COMSOL myself. all these damn things come from the physics induced sequence.


next time cannot converge the model., right click mesh edit the physics induced sequence, then set the minimum order to be smaller then you can solve any model.

Ivar kjelberg after so many years you are still the best mentor on the forum. thanks for tips.

matlab ubuntu remote control and python2 to python3

Today manage to using remote control on the ubuntu

1. you can turn on the screen sharing using privary setting and ask it to just use the password,
then you can on remina from virtual ubuntu to remote access it
or you can also use windows
instal the vnc viewer
https://www.howtogeek.com/429190/how-to-set-up-remote-desktop-on-ubuntu/

2. also I manage to install matlab on ubuntu
https://linuxconfig.org/how-to-install-matlab-on-ubuntu-18-04-bionic-beaver-linux

3.         try:
            val_local = w.vector()(val_dof[0])

from dolfin import *
from ufl import cofac
import dolfin as dolfin
import sys

import
from ufl import cofac

mesh = Mesh()
f = HDF5File(MPI.comm_world, meshname+".hdf5", 'r')

print(tstep, p_cav*0.0075 , V_cav, fdataPV)

use 2to3 convert print function from python2 to python3
sudo apt-get 2to3

mesh = Mesh()
f = HDF5File(MPI.comm_world, meshname+".hdf5", 'r')
