How do you connect to a remote server via IP address in the manner that TOAD, SqlDeveloper, are able to connect to databases with just the ip address, username, SID and password? Whenever I try to specify and IP address, it seems to be taking it locally. In other words, how should the string for cx\_Oracle.connect() be formatted to a non local database? There was a previous post which listed as an answer connecting to Oracle via cx\_Oracle module with the following code: ``` #!/usr/bin/python import cx_Oracle connstr='scott/tiger' conn = cx_Oracle.connect(connstr) curs = conn.cursor() curs.execute('select * from emp') print curs.description for row in curs: print row conn.close() ```

I like to do it this way: ``` ip = '192.168.0.1' port = 1521 SID = 'YOURSIDHERE' dsn_tns = cx_Oracle.makedsn(ip, port, SID) db = cx_Oracle.connect('username', 'password', dsn_tns) ``` One of the main reasons I like this method is that I usually have a TNSNAMES.ORA file lying around someplace, and I can check that the `dsn_tns` object will do the right thing by doing: ``` print dsn_tns ``` and comparing the output to my TNSNAMES.ORA

```py import cx_Oracle dsn = cx_Oracle.makedsn(host='127.0.0.1', port=1521, sid='your_sid') conn = cx_Oracle.connect(user='your_username', password='your_password', dsn=dsn) conn.close() ```

You can specify the server in the connection string, e.g.: ``` import cx_Oracle connstr = 'scott/tiger@server:1521/orcl' conn = cx_Oracle.connect(connstr) ``` * "server" is the server, or the IP address if you want. * "1521" is the port that the database is listening on. * "orcl" is the name of the instance (or database service).

``` import cx_Oracle CONN_INFO = { 'host': 'xxx.xx.xxx.x', 'port': 12345, 'user': 'user_name', 'psw': 'your_password', 'service': 'abc.xyz.com', } CONN_STR = '{user}/{psw}@{host}:{port}/{service}'.format(**CONN_INFO) connection = cx_Oracle.connect(CONN_STR) ```

I'm trying to convert the command line return of `docker container ls -q` into a python list using the os.system library and method. Is there a way to do this using the os library? Essentially I'm trying to check if there are any running containers before I proceed through my code. Thanks in advance!

Using `src` in the `img` tag to render image ``` <img className="icon" key={item.weather[0].icon} src={`https://openweathermap.org/img/w/${item.weather[0].icon}.png`} /> ``` And put the key in `div` instead in the children.

Not sure why you are doing it, but setting JSX in your state seems strange. Try something like this, assuming `res2.data.list` has the list of values. ``` <div className="five_day_forecast"> <div className="temp_body"> // Display here with Date/Time & Main Temp. <p> {res2.data.list && res2.data.list.length >0 && res2.data.list.map(item => [ <div className="each_data_point"> <li className="date_time" key={item.dt_txt}>{`Date & Time: ${ item.dt_txt }`}</li> , <img className="icon" key={item.weather[0].icon} >{`https://openweathermap.org/img/w/${ item.weather[0].icon }.png`}</img> , <li className="main_temp" key={item.main.temp}>{`Temp: ${ item.main.temp }`}</li> </div> ])} </p> </div> </div> ```

Putting markup in state is a weird anti-pattern. State is really there to just store *data* not markup. You can use a function to create the JSX from `map`ping over the data. You should be adding the source of the image to the `src` attribute of the `img` element. Keys should be added to parent elements. ``` const imgSrc = `https://openweathermap.org/img/w/${item.weather[0].icon}.png`; <img src={imgSrc} /> ``` ```js // `fetch` your data, and add it to state setForecast(res2.data.list); // `map` over the data and create the markup function getMarkup() { const imgSrc = `https://openweathermap.org/img/w/${item.weather[0].icon}.png`; return forecast.map(item => { <div className="each_data_point" key={item.dt_txt}> <li className="date_time">{`Date & Time: ${item.dt_txt}`}</li>, <img src={imgSrc} className="icon" />, <li className="main_temp">{`Temp: ${item.main.temp}`}</li> </div> }); } return ( <div> <div className="five_day_forecast"> <div className="temp_body"> // Call the function to return the markup // build from state {getMarkup()} </div> </div> ); ```

I'm trying to set up travis build with JDK13, using for it two ways - by setting `jdk` parameter to `openjdkea` - by downloading jdk and setting env variables (installation tested locally), And still `java --version` is 1.8 and it is used in runtime, even maven uses jdk13 for build. Here is my `travis.yml`: ``` language: "perl" perl: - "5.14" - "5.26" git: depth: false sudo: false jdk: - openjdk-ea addons: apt: packages: - python3 - maven - graphviz before_install: - wget https://download.java.net/java/early_access/jdk13/21/GPL/openjdk-13-ea+21_linux-x64_bin.tar.gz - tar xvzf openjdk-13-ea+21_linux-x64_bin.tar.gz - export JAVA_HOME=$PWD/jdk-13 - export PATH=$PATH:$JAVA_HOME/bin - ls $JAVA_HOME - java -version - javac -version - mvn -version - mysql --version - sqlite3 --version - env - cd wrappers/java - mvn clean - mvn package - cd ../.. install: - cpanm -v --installdeps --with-recommends --notest . - cpanm -n Devel::Cover::Report::Coveralls - cpanm -n Devel::Cover::Report::Codecov script: "./scripts/dev/travis_run_tests.sh" ``` And here in output you can see java --version is 1.8 that causes test fail, even maven uses jdk13-ea for build. ``` java -version java version "1.8.0_151" Java(TM) SE Runtime Environment (build 1.8.0_151-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode) travis_time:end:23204870:start=1558602135904104138,finish=1558602136218922843,duration=314818705 [0Ktravis_fold:end:before_install.18 [0Ktravis_fold:start:before_install.19 [0Ktravis_time:start:16b0d9da [0K$ javac -version javac 1.8.0_151 travis_time:end:16b0d9da:start=1558602136223048229,finish=1558602136845508635,duration=622460406 [0Ktravis_fold:end:before_install.19 [0Ktravis_fold:start:before_install.20 [0Ktravis_time:start:346a8d88 [0K$ mvn -version Apache Maven 3.0.5 Maven home: /usr/share/maven Java version: 13-ea, vendor: Oracle Corporation Java home: /home/travis/build/Ensembl/jdk-13 Default locale: en_US, platform encoding: UTF-8 ``` What am I doing wrong, how to correctly set new JDK?

As loadChildren:string is deprecated in angular 8 Change your loadChildren declarations From ``` loadChildren: './production/production.module#ProductionModule' ``` To ``` loadChildren: () => import('./production/production.module').then(m => m.ProductionModule) ``` For more you can ref angular official [git link](https://github.com/angular/angular/pull/30073) and [commit](https://github.com/angular/angular/commit/c61df39)

Apparently, it's not the entire `"loadChildren" : ...` which is deprecated. It just will no longer accept strings. Instead you have to specify a function now. The documentation is already available [here](https://fireship.io/snippets/lazy-loaded-routes-angular-v8-ivy/). It comes down to: ``` const routes = [ { path: 'lazy', loadChildren : () => import('./production/production.module').then(m => m.ProductionModule), } ]; ```

Within brackets, python's slice shorthand auto-generates tuples of slice objects: ``` class Foo(object): def __getitem__(self, key): print key Foo()[1::, 2:20:5] ``` This prints `(slice(1, None, None), slice(2, 20, 5))`. As far as I can tell, however, this shorthand doesn't work outside brackets. Is there any way to use slice shorthand in other contexts? I could define a dummy object that simply returns whatever it is passed to `__getitem__` -- that would at least give me a way to generate slice tuples using the shorthand syntax. Is there a more pythonic way?

NumPy has an [`s_`](http://docs.scipy.org/doc/numpy/reference/generated/numpy.s_.html) object that will do this for you: ```none >>> np.s_[2::2] slice(2, None, 2) ``` You can easily make your own version of this simply by setting `s_ = Foo()` and then using `s_` whenever you want to create a slice easily.

What you see printed out is actually a good clue. You can create slice objects directly through the slice() global function. These can then be passed used to index from lists. ``` s = slice(1, 10, 2) numbers = list(range(20)) print numbers[s] print numbers[1:10:2] ``` This will print the same result twice, [1, 3, 5, 7, 9]. The slice instances have a few attributes and methods. You can look at help(slice) to see more.

In Ruby one can inspect a variable (object) by `p my_obj` so it'll print it as "deep" and in detail as possible. It's useful for logging and debugging. In python I thought it was `print my_obj`, only it didn't print much but `<requests.sessions.Session object at 0x7febcb29b390>` which wasn't useful at all. How do I do this?

`dir()` will probably give you what you want: ``` for key in dir(my_obj): print('{}: {}'.format(key, getattr(my_obj, key))) ``` There's a lot more information there that you're expecting though, if I had to guess :)

That is the most universal way to "print" an object, it's just that not every object will have a very useful printout; most probably don't, in fact. If you're working with an object someone else created, you'll often want to look at the documentation to find out how to look at its variables and whatnot. That will often give you the prettiest output. Other answers to this question offer a more general way of inspecting an object, which can be a lot faster and easier than looking up documentation; they do a more shallow inspection, as far as I can tell, but they're a good starting point. If you're making your own object, you'll want to define a method called `__str__()` that returns a string. Then, whenever you say `print obj`, that object's `__str__()` function will be called, and that string will be returned. In your case, if you have a `request.Session()` object named `my_obj`, you can apparently print it with `print(my_obj.text)`, according to the documentation. <http://docs.python-requests.org/en/latest/user/advanced/>

If you want complete control over printing for the object, define the `__repr__` and `__str__` functions for your class. ``` class Node(object): """ A node object with an index""" def __init__(self,index = 0): self.index = index def __repr__(self): print "Node %s" % self.index def __str__(self): print "Node %s" % self.index ``` Sometimes you will want to see the detailed information, so only overwriting `__str__` is probably a good idea.

You can use [`vars`](https://docs.python.org/2/library/functions.html#vars) builtin method to get a dictionary of the object's attributes: ``` >>> import requests >>> r = requests.Session() >>> vars(r) {'cookies': <<class 'requests.cookies.RequestsCookieJar'>[]>, 'stream': False, 'hooks': {'response': []}, 'auth': None, 'trust_env': True, ...} ``` Maybe combine it with [`pprint`](https://docs.python.org/2/library/pprint.html) to get a somewhat formatted output: ``` >>> import pprint >>> pprint.pprint(vars(r), indent=2) { 'adapters': OrderedDict([('https://', <requests.adapters.HTTPAdapter object at 0x103106690>), ('http://', <requests.adapters.HTTPAdapter object at 0x103106790>)]), 'auth': None, 'cert': None, 'cookies': <<class 'requests.cookies.RequestsCookieJar'>[]>, ... ```

First, I select 1.0.8 version of stocator ... ``` !pip install --user --upgrade pixiedust import pixiedust pixiedust.installPackage("com.ibm.stocator:stocator:1.0.8") ``` Restarted kernel, then ... ``` access_key = 'xxxx' secret_key = 'xxxx' bucket = 'xxxx' host = 'lon.ibmselect.objstor.com' hconf = sc._jsc.hadoopConfiguration() hconf.set("fs.s3d.service.endpoint", "http://" + host) hconf.set("fs.s3d.service.access.key", access_key) hconf.set("fs.s3d.service.secret.key", secret_key) file = 'mydata_file.tsv.gz' inputDataset = "s3d://{}.service/{}".format(bucket, file) lines = sc.textFile(inputDataset, 1) lines.count() ``` However, that results in the following error: ``` Py4JJavaError: An error occurred while calling z:org.apache.spark.api.python.PythonRDD.collectAndServe. : java.lang.AbstractMethodError: com/ibm/stocator/fs/common/IStoreClient.setStocatorPath(Lcom/ibm/stocator/fs/common/StocatorPath;)V at com.ibm.stocator.fs.ObjectStoreFileSystem.initialize(ObjectStoreFileSystem.java:104) at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2669) at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:94) at org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2703) at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:2685) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:373) at org.apache.hadoop.fs.Path.getFileSystem(Path.java:295) at org.apache.hadoop.mapred.FileInputFormat.singleThreadedListStatus(FileInputFormat.java:258) at org.apache.hadoop.mapred.FileInputFormat.listStatus(FileInputFormat.java:229) at org.apache.hadoop.mapred.FileInputFormat.getSplits(FileInputFormat.java:315) at org.apache.spark.rdd.HadoopRDD.getPartitions(HadoopRDD.scala:199) at org.apache.spark.rdd.RDD$$anonfun$partitions$2.apply(RDD.scala:251) at org.apache.spark.rdd.RDD$$anonfun$partitions$2.apply(RDD.scala:249) at scala.Option.getOrElse(Option.scala:121) at org.apache.spark.rdd.RDD.partitions(RDD.scala:249) at org.apache.spark.rdd.MapPartitionsRDD.getPartitions(MapPartitionsRDD.scala:35) at org.apache.spark.rdd.RDD$$anonfun$partitions$2.apply(RDD.scala:251) at org.apache.spark.rdd.RDD$$anonfun$partitions$2.apply(RDD.scala:249) at scala.Option.getOrElse(Option.scala:121) at org.apache.spark.rdd.RDD.partitions(RDD.scala:249) at org.apache.spark.api.python.PythonRDD.getPartitions(PythonRDD.scala:53) at org.apache.spark.rdd.RDD$$anonfun$partitions$2.apply(RDD.scala:251) at org.apache.spark.rdd.RDD$$anonfun$partitions$2.apply(RDD.scala:249) at scala.Option.getOrElse(Option.scala:121) at org.apache.spark.rdd.RDD.partitions(RDD.scala:249) at org.apache.spark.SparkContext.runJob(SparkContext.scala:1927) at org.apache.spark.rdd.RDD$$anonfun$collect$1.apply(RDD.scala:932) at org.apache.spark.rdd.RDDOperationScope$.withScope(RDDOperationScope.scala:151) at org.apache.spark.rdd.RDDOperationScope$.withScope(RDDOperationScope.scala:112) at org.apache.spark.rdd.RDD.withScope(RDD.scala:378) at org.apache.spark.rdd.RDD.collect(RDD.scala:931) at org.apache.spark.api.python.PythonRDD$.collectAndServe(PythonRDD.scala:453) at org.apache.spark.api.python.PythonRDD.collectAndServe(PythonRDD.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:95) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:55) at java.lang.reflect.Method.invoke(Method.java:507) at py4j.reflection.MethodInvoker.invoke(MethodInvoker.java:237) at py4j.reflection.ReflectionEngine.invoke(ReflectionEngine.java:357) at py4j.Gateway.invoke(Gateway.java:280) at py4j.commands.AbstractCommand.invokeMethod(AbstractCommand.java:132) at py4j.commands.CallCommand.execute(CallCommand.java:79) at py4j.GatewayConnection.run(GatewayConnection.java:214) at java.lang.Thread.run(Thread.java:785) ``` ​**Note:** My first attempt at connecting to IBM COS resulted in a different error.

No need to install stocator it is already there. As Roland mentioned, new installation most likely would collide with the pre-installed one and cause conflicts. Try ibmos2spark: <https://stackoverflow.com/a/46035893/8558372> Let me know if you still facing problems.

Chris, I usually don't use the 'http://' in the endpoint and that works for me. Not sure if that is the problem here.

I highly recommend the Spark aaS documentation at: <https://console.bluemix.net/docs/services/AnalyticsforApacheSpark/index-gentopic1.html#genTopProcId2> Please choose the correct COS endpoints from: <https://ibm-public-cos.github.io/crs-docs/endpoints> and PLEASE use the private endpoints if you're working from within the IBM Cloud. It will be much faster and cheaper. It's got examples of how to access COS data using all the nice helpers.

I kind of know why when I do `migrate` it gives me the message of `no migrations to apply` but I just don't know how to fix it This is what happens. I added a new field named `update` into my model fields. I did a `migration` which created a file called `0003_xxxxx.py` then I did a `migrate` now this worked fine. But then because of some reason, I have to remove the `update` field from the same model. So I removed it (more likey commented instead of really delete the code) then I did `migration` and `migrate` which removed the field in db. (created `0004_xxxxx.py`) But sigh....some reason I have to add the field back again (this is why I only commented out) but then before I do the `migration` I removed the `0003_xxxx.py and 0004_xxxx.py` files I wanted to remove those two files because this is actually the same or almost the same config as `0003_xxxx.py` so I feel it's pointless having the `0003_xxxx.py and 0004_xxxx.py` here...also when I go production, that's just another extra step for python to run. After I removed those two files, I did the `migration` which creates another `0003_xxxx.py` but when I do `migrate` it gives me the message of `no migrations to apply` I know that by deleting the `0003_xxxx.py` and get the original `0003 and 0004` back then do another `migration (creates 0005_xxxx.py) then migrate` then changes will be made. I know this because I didn't really delete the original `0003 and 0004` I moved it somewhere just in case of this kind of happening. But why is this though? and is there a way to fix it? Thanks in advance for any replies

django keep records of current `migrations` log by table `django_migrations` in your db. something like: [](https://i.stack.imgur.com/4iFvO.jpg) The migrations is a chain structure,it's depend on the parent node.By this table django can know which migrations file is executed. In you case,`no migrations to apply` because the new create `0003_xxxx.py` is record in this table,you can fix it by delete this record in this table. If you want remove some migration file you need see [Squashing migrations](https://docs.djangoproject.com/en/2.0/topics/migrations/#squashing-migrations).

Or even simply just delete the last migration row from your database you can try the following First, check which row you want to remove ``` SELECT * FROM "public"."django_migrations"; ``` Now pick the last `id` from the above query and execute ``` DELETE FROM "public"."django_migrations" WHERE "id"=replace with your Id; ``` run `./manage.py migrate`.

I know this because I didn't really delete the original `0003 and 0004` I moved it somewhere just in case of this kind of happening. But why is this though? and is there a way to fix it? Thanks in advance for any replies

django keep records of current `migrations` log by table `django_migrations` in your db. something like: [](https://i.stack.imgur.com/4iFvO.jpg) The migrations is a chain structure,it's depend on the parent node.By this table django can know which migrations file is executed. In you case,`no migrations to apply` because the new create `0003_xxxx.py` is record in this table,you can fix it by delete this record in this table. If you want remove some migration file you need see [Squashing migrations](https://docs.djangoproject.com/en/2.0/topics/migrations/#squashing-migrations).

just run: ``` python manage.py run --run-syncdb ```

I kind of know why when I do `migrate` it gives me the message of `no migrations to apply` but I just don't know how to fix it This is what happens. I added a new field named `update` into my model fields. I did a `migration` which created a file called `0003_xxxxx.py` then I did a `migrate` now this worked fine. But then because of some reason, I have to remove the `update` field from the same model. So I removed it (more likey commented instead of really delete the code) then I did `migration` and `migrate` which removed the field in db. (created `0004_xxxxx.py`) But sigh....some reason I have to add the field back again (this is why I only commented out) but then before I do the `migration` I removed the `0003_xxxx.py and 0004_xxxx.py` files I wanted to remove those two files because this is actually the same or almost the same config as `0003_xxxx.py` so I feel it's pointless having the `0003_xxxx.py and 0004_xxxx.py` here...also when I go production, that's just another extra step for python to run.

Or even simply just delete the last migration row from your database you can try the following First, check which row you want to remove ``` SELECT * FROM "public"."django_migrations"; ``` Now pick the last `id` from the above query and execute ``` DELETE FROM "public"."django_migrations" WHERE "id"=replace with your Id; ``` run `./manage.py migrate`.

just run: ``` python manage.py run --run-syncdb ```

Instead of copying Swig files to the Python folder, you can simply add Swig`s location to the environment variables: 1. Press `Ctrl+S` 2. Type `env` and press `Enter` 3. Double click on `Path` 4. Add the *path-to-Swig* to the last blank line 5. Click `OK` and restart your PC

I know I am late, but what worked for me was to download the pre-built wheel file and install it manually (tested on Windows. I am pretty sure it will only work on Windows). [https://www.lfd.uci.edu/~gohlke/pythonlibs/#pocketsphinx](https://www.lfd.uci.edu/%7Egohlke/pythonlibs/#pocketsphinx) Just grab the right one (cp39 = python 3.9). When it finishes downloading, navigate to your downloads folder in cmd, and issue the following command: ```bash pip install pocketsphinx-0.1.15-cp39-cp39-win_amd64.whl ``` **NOTE**: Change `pocketsphinx-0.1.15-cp39-cp39-win_amd64.whl` to the name of the whl file you downloaded. I grabbed this one because I use Python 3.9 64bit version.

In case you are working on anaconda navigator. Just go to environment. Search swig, your package will be displayed. Select the package and click on apply button. It will also give a prompt list of other dependencies, which need to be installed with swig. So just select all and click on apply button. All the dependencies will be installed in your root directory of anaconda. This worked for me, hope it helps.

For a purely pip-based fix (may or not work depending on your exact issue/system): ``` pip install swig pip install pocketsphinx pip freeze > requirements.txt ``` Fixed the issue simply for me. With pip freeze, you're likely to not have the issue again if cloning the project in another system (since swig will be installed just with `pip install -r requirements.txt`) This is the kind of things for which it becomes REALLY worthwhile to look into using virtualenv or similar, instead of polluting (and endlessly re-configuring) your system.

To fix the problem, I downloaded [swig for windows](https://netix.dl.sourceforge.net/project/swig/swigwin/swigwin-3.0.12/swigwin-3.0.12.zip) at the time of writing this answer it was 3.0.12 [For the latest swig windows version follow this link](http://www.swig.org/download.html) 1. Copy swig.exe to the python installation folder (for ex C:/python27) 2. Open the `swigwin-3.0.12/Lib` folder and copy all `*.swg` files to the `C:/python27/Lib` or equivalent python path 3. Open `swigwin-3.0.12/Lib/python` and copy all the files to `C:/python27/Lib` 4. Open the `swigwin-3.0.12/Lib` folder and copy over the `typemaps` folder to `C:/python27/Lib` (Also make sure you have Microsoft Visual C++ Compiler for Python installed) These steps worked for me.

I was also getting same error, while installing in ubuntu 16.04, I executed following commands: ``` sudo apt-get install -y python python-dev python-pip build-essential swig git libpulse-dev sudo pip install pocketsphinx ``` source: [pocketsphinx-python](https://github.com/cmusphinx/pocketsphinx-python)

You try to install `pocketsphinx` with `pip`, that will download and compile this module. It requires some compiling tool like `swig`. Another solution is to install a binary version of `pocketsphinx`. You can download a binary version [here](http://www.lfd.uci.edu/~gohlke/pythonlibs/#pocketsphinx). You have to select the correct version with respect to your installation. To determine which one you have to download, you can run the following commands, that will tell you which version you require and whether you run a 32 or 64 bit python interpreter. ``` "C:\Users\krush\Anaconda3\python.exe" --version "C:\Users\krush\Anaconda3\python.exe" -c "import struct;print(struct.calcsize('P') * 8)" ``` Below are some commands that you may enter once you have downloaded the correct version ``` "C:\Users\krush\Anaconda3\python.exe" -m pip install pocketsphinx‑0.1.3‑cp35‑cp35m‑win32.whl "C:\Users\krush\Anaconda3\python.exe" -m pip install pocketsphinx‑0.1.3‑cp36‑cp36m‑win_amd64.whl ```

There are few set of commands to resolve this. Just execute them: ``` sudo apt-get install -y python3 python3-dev python3-pip build-essential swig git libpulse-dev sudo apt-get install libasound2-dev sudo pip install pocketsphinx ```

I know I am late, but what worked for me was to download the pre-built wheel file and install it manually (tested on Windows. I am pretty sure it will only work on Windows). [https://www.lfd.uci.edu/~gohlke/pythonlibs/#pocketsphinx](https://www.lfd.uci.edu/%7Egohlke/pythonlibs/#pocketsphinx) Just grab the right one (cp39 = python 3.9). When it finishes downloading, navigate to your downloads folder in cmd, and issue the following command: ```bash pip install pocketsphinx-0.1.15-cp39-cp39-win_amd64.whl ``` **NOTE**: Change `pocketsphinx-0.1.15-cp39-cp39-win_amd64.whl` to the name of the whl file you downloaded. I grabbed this one because I use Python 3.9 64bit version.

In reference to this question: [python: Two modules and classes with the same name under different packages](https://stackoverflow.com/questions/15720593/python-two-modules-and-classes-with-the-same-name-under-different-packages) Should all modules in a package be uniquely named, regardless of nesting? PEP8 and PEP423 do not seem to address this.

No, there is no requirement that names at different levels must be different. Each level is a separate namespace. If `foo.utils` and `foo.bar.utils` make sense in your project, just do so. For example, the Python standard library has [`email.message`](https://docs.python.org/3/library/email.message.html) and [`email.mime.message`](https://docs.python.org/3/library/email.mime.html?highlight=email.mime.message#email.mime.message.MIMEMessage), and [`multiprocessing.connection`](https://docs.python.org/3/library/multiprocessing.html#module-multiprocessing.connection), as well as [`multiprocessing.dummy.connection`](https://docs.python.org/3/library/multiprocessing.html#module-multiprocessing.dummy), and many more: ``` $ ls ~/Development/Library/cpython/Lib/**/*.py | grep -v __ | grep -v test_ | xargs basename | sort | uniq -c | grep -v ' 1 ' | sort 2 abc.py 2 ascii.py 2 client.py 2 connection.py 2 constants.py 2 dump.py 2 errors.py 2 filelist.py 2 handlers.py 2 log.py 2 message.py 2 parse.py 2 parser.py 2 process.py 2 queues.py 2 server.py 2 spawn.py 2 text.py 2 tree.py 3 main.py 4 config.py 5 support.py 6 util.py ``` That's all modules that appear inside packages, appear more than once, excluding tests, `__init__.py` and `__main__.py`.

Since package is based on the filesystem, you can not, in normal circonstance, have the same packages because files/directories have no duplicate. You can have the same namespace package, of course. It is also possible to have the same package/module name in different paths. They are searched in order, so the first win.

Please help.

Theano do not support Visual Studio compiler. It is needed for cuda, but not for Theano CPU code. This need g++ compiler. Is the canopy package for the compiler correctly installed? What did you do to try to compile with microsoft compiler?

Windows Canopy, like all standard CPython 2.7 distributions for Windows, is compiled with Visual C++ 2008, and that is the compiler that you should use for compiling all non-trivial C extensions for it. The following article includes some links for obtaining this compiler: <https://support.enthought.com/entries/26864394-Windows-Unable-to-find-vcvarsall-bat-cython-f2py-other-c-extensions->
